b2ed7a03
AC		 1402009-04-16 Olivier Hainque <hainque@adacore.com>
141

AC		 1652009-04-15 Hristian Kirtchev <kirtchev@adacore.com>
166
167 * exp_ch9.adb: Comment improvements.
168 (Build_Entry_Family_Name): Add parentheses around the index of a entry
169 family member.
170
1712009-04-15 Bob Duff <duff@adacore.com>
172
173 * sem_warn.adb (Check_Infinite_Loop_Warning): Catch cases like
174 "while X /= null loop" where X is unchanged inside the loop. We were
175 not warning in this case, because of the pointers -- we feared that the
176 loop variable could be updated via a pointer, if there are any pointers
177 around the place. But that is impossible in this case.
178
179 * sem_util.adb (May_Be_Lvalue): This routine was overly pessimistic in
180 the case of dereferences. In X.all, X cannot be an l-value. We now
181 catch that case (and implicit dereferences, too).
182
1832009-04-15 Vincent Celier <celier@adacore.com>
184
185 * sinput-p.ads, sinput-p.adb (Clear_Source_File_Table): New procedure

190 From code reading.
191 (Analyze_Package_Instantiation): If generic unit in child instance is
192 the same as generic unit in parent instance, look for an outer homonym
193 to locate the desired generic.
194
4a13695c
AC		 1952009-04-15 Bob Duff <duff@adacore.com>
196
197 * sem_ch5.adb (Analyze_Loop_Statement): Don't check for infinite loop
198 warnings unless the loop comes from source, because checking generated
199 loops is a waste of time, and makes it harder to debug
200 Check_Infinite_Loop_Warning.
201
202 * sem_warn.adb (Check_Infinite_Loop_Warning): If the local variable
203 tested in the while loop is a renaming, do not warn. Otherwise, we get
204 false alarms, because it's usually renaming something that we can't
205 deal with (an indexed component, a global variable, ...).
206
207 * gnat_rm.texi: Fix typo
208
2092009-04-15 Thomas Quinot <quinot@adacore.com>

216 immediate parent of the controlled function call is a component
217 association.

231 (Write_Unit): Add new parameter Write_BOM
232 (Write_Chopped_Files): Check for BOM and set Write_BOM for call
233 to Write_Unit
234
235 * gnat_ugn.texi: Add note on propagation of BOM by gnatchop
236
2372009-04-15 Geert Bosch <bosch@adacore.com>

248
249 * exp_ch7.adb (Expand_Ctrl_Function_Call): Procede with the expansion
250 of a controlled function call in the context of a record aggregate.
251 This does not apply to array aggregates since the call will be expanded
252 into assignments.
253
2542009-04-15 Ed Falis <falis@adacore.com>
255
256 * s-osinte-vxworks-kernel.adb, s-osinte-vxworks.adb,

287
2882009-04-15 Ed Schonberg <schonberg@adacore.com>
289
290 * exp_ch6.adb (Expand_Inlined_Call): If an in-parameter in a call to be
291 inlined is of an array type that is not bit-packed, use a renaming
292 declaration to capture its value, rather than a constant declaration.

7349 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
7350 convention from its base type, do not set the type to that of integer,

7391
7392 * par-ch3.adb
7393 (P_Access_Definition): Change the error message when parsing "access
7394 all" in Ada 95 mode. The message no longer forces the user to recompile
7395 in 05 mode only to discover that anonymous access types are not allowed
7396 to have "all".

7414 (Set_Categorization_From_Scope): Do not set In_Remote_Types unless in
7415 the visible part of the spec of a remote types unit.
7416 (Validate_Remote_Access_Object_Type_Declaration):
7417 New local subprogram Is_Valid_Remote_Object_Type, replaces
7418 Is_Recursively_Limited_Private.
7419 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
7420 non-controlling formals (and the return type, even though this is not
7421 explicit in the standard) must support external streaming.
7422 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
7423 as above for of RAS types and RCI subprograms. (The return type is not
7424 checked yet).
7425 Update comments related to RACWs designating limited interfaces per
7426 ARG ruling on AI05-060.
7427
7428 * sem_util.ads, sem_util.adb
7429 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
7430 Is_Remote_Call_Interface to identify RACW types in a stable and
7431 consistent way. We used to rely in this predicate on the privateness of
7432 the designated type and its ancestors, but depending on the currently
7433 visible private parts, this caused false negatives. We now uniformly
7434 rely on checks made at the point where the RACW type is declared.
7435 (Inspect_Deferred_Constant_Completion): Moved from Sem_Ch7.

7442 (Analyze_Object_Declaration): Fix over-conservative condition
7443 restricting use of predefined assignment with tagged types that have
7444 convention CPP.
7445 (Analyze_Object_Declaration): Relax the check regarding deferred
7446 constants declared in scopes other than packages since they can be
7447 completed with pragma Import.
7448 Add missing escaping of all-caps word 'CPP' in error messages.
7449 (Build_Discriminated_Subtype): Do not inherit representation clauses
7450 from parent type if subtype already carries them, because they are
7451 inherited earlier during derivation and already include those that may
7452 come from a partial view.
7453
7454 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):

7466 F is a parameterless function that returns an array, and S is a subtype
7467 mark.
7468 (Analyze_Call): Insert dereference when the prefix is a parameterless
7469 function that returns an access to subprogram and the call has
7470 parameters.
7471 Reject a non-overloaded call whose name resolves to denote
7472 a primitive operation of the stub type generated to support a remote
7473 access-to-class-wide type.

7489 (Add_One_Interp): Ignore any interpretation that is a primitive
7490 operation of an RACW stub type (these primitives are only executed
7491 through dispatching, never through static calls).
7492 (Collect_Interps): When only one interpretation has been found, set N's
7493 Entity and Etype to that interpretation, otherwise Entity and Etype may
7494 still refer to an interpretation that was ignored by Add_One_Interp,
7495 in which case would end up with being marked as not overloaded but with
7496 an Entity attribute not pointing to its (unique) correct interpretation.

11323 (Check_Version_And_Help): Change Check_Version_And_Help to be generic,
11324 with a parameter "procedure Usage", instead of passing a pointer to a
11325 procedure. This is to eliminate trampolines (since the Usage procedure
11326 is often nested in a main procedure, and it would be inconvenient to
11327 unnest it).
11328
11329 * g-comlin.adb (For_Each_Simple_Switch): Change For_Each_Simple_Switch
11330 to be generic, with a parameter "procedure Callback (...)", instead of

113722007-12-13 Ed Schonberg <schonberg@adacore.com>
11373
11374 * exp_aggr.adb (Build_Record_Aggr_Code): If there is an aggregate for a
11375 limited ancestor part, initialize controllers of enclosing record
11376 before expanding ancestor aggregate.
11377 (Gen_Assign): If a component of the aggregate is box-initialized, add
11378 code to call Initialize if the component is controlled, and explicit
11379 assignment of null if the component is an access type.
11380

11398 type of formal Renamed_Eq to Entity_Id (instead of Node_Id).
11399 (Make_Predefined_Primitive_Specs): Spec of "=" needed if the parent is

11407 function.
11408 Add also bodies of predefined primitives associated with synchronized
11409 interfaces.
11410 (Freeze_Record_Type): Do not build bodies of predefined primitives of

11490
11491 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing

11510 mismatches in gigi.
11511 (Resolve_Actuals): If the actual is an entity name, generate a
11512 reference before the actual is resolved and expanded, to prevent
11513 spurious warnings on formals of enclosing protected operations.

11515 class-wide, use visible components of base type.
11516 (Resolve_Selected_Component): Ditto.

11538
11539 * layout.adb (Resolve_Attribute, case 'Access): If designated type of

11541 non-limited view is an unconstrained array, this enforces consistency
11542 requirements in 3.10.2 (27).
11543 (Layout_Type): For an access type whose designated type is a limited
11544 view, examine its declaration to determine if it is an unconstrained
11545 array, and size the access type accordingly.
11546 (Layout_Type): Do not force 32-bits for convention c subprogram
11547 pointers in -gnatdm mode, only if real vms target.
11548
11549 * sem_attr.adb (Analyze_Access_Attribute): Use new flag

11551 (Analyze_Access_Attribute,Attribute_Address): Remove checks for
11552 violations of the No_Implicit_Dynamic_Code restriction.
11553 (Resolve_Attribute, case 'Access): If designated type of context is a

11556 in 3.10.2 (27).
11557 (Layout_Type): For an access type whose designated type is a limited
11558 view, examine its declaration to determine if it is an unconstrained
11559 array, and size the access type accordingly.

11613 Do not give warning on exception raise in No_Return function
11614
11615 * sem_ch13.adb (Analyze_Record_Representation_Clause): If an inherited
11616 component has two inconsistent component clauses in the same record
11617 representation clause, favor the message that complains about
11618 duplication rather than inconsistency.
11619 Update comments.
11620 (Record_Representation_Clause): Do not warn on missing component
11621 clauses for inherited components of a type extension.
11622 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
11623 an overloadable item if it is a pragma that can apply to multiple
11624 overloadable entities (e.g. Inline) because a pragma cannot be on
11625 more than one chain at a time.
11626 (Validate_Unchecked_Conversion): Add code to warn on unchecked
11627 conversion where one of the operands is Ada.Calendar.Time.
11628 (Analyze_Attribute_Definition_Clause): Fix typo in error message.

11640 (prj-nmsc.adb): Optimize calls to Name_Find when on case sensitive
11641 systems, since we do not need to recompute the Name_Id for the canonical
11642 file name.
11643 (Body_Suffix_Id_Of, Spec_Suffix_Id_Of): new version that takes a name_id
11644 as a parameter. This parameter is in fact always "ada" in all calls, and

11679 subunit), always consider the longest suffix.
11680 (Check_Configuration): Do not issue an error if there is no compiler
11681 for a language. Just issue a warning and ignore the sources for the
11682 language.

11684 not empty.
11685 (Check_Naming_Schemes.Maked_Unit): Only output message if high verbosity
11686 (Unit_Exceptions): New hash table
11687 (Check_Naming_Schemes): Check if a file that could be a unit because of
11688 the naming scheme is not in fact a source because there is an exception
11689 for the unit.

11717 Locate_Regular_File is a costly routine. The code to output a log
11718 information and the effective call to Locate_Regular_File is now
11719 factorized into a routine (code clean-up).

11758 child unit is a renaming, create an implicit with_clause on that
11759 parent, and not on the unit it renames, to prevent visibility errors
11760 in the current unit.
11761
117622007-12-13 Ed Schonberg <schonberg@adacore.com>
11763
11764 * sem_ch12.adb (Instantiate_Formal_Subprogram): In the subprogram
11765 renaming declaration, use the Slocs of the formal parameters from the
11766 declaration of the formal subprogram when creating the formal parameter
11767 entities in the renaming declaration.
11768 (Analyze_Formal_Type_Declaration): Change the placement of the error
11769 message concerning illegal known discriminants. It is now posted on the
11770 type rather than on the first discriminant. This change ensures early
11771 error report.
11772 (Freeze_Subprogram_Body): If the generic subprogram is nested within
11773 the package body that contains the instance, do not generate an
11774 out-of-place freeze node for the enclosing package.
11775 (Collect_Previous_Instantiations): Ignore internal instantiations
11776 generated for formal packages.
11777 (Validate_Derived_Type_Instance): Add a check that when a formal

11795
11796 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Avoid
11797 generation of spurious error if parent is an interface type; caused
11798 because predefined primitive bodies will be generated later by
11799 Freeze_Record_Type.
11800 (Process_Subtype): The subtype inherits the Known_To_Have_Preelab_Init
11801 flag.
11802 (Derive_Subprograms): Handle derivations of predefined primitives
11803 after all the user-defined primitives to ensure that they are
11804 found in proper order in instantiations.
11805 (Add_Interface_Tag_Components, Inherit_Components): Update occurrences
11806 of Related_Interface to Related_Type.
11807 (Record_Type_Declaration): Minor reordering of calls to decorate the

11809 before setting its Is_Tag attribute.
11810 (Analyze_Subtype_Declaration): In the case of subtypes with
11811 Private_Kind, inherit Known_To_Have_Preelab_Init from the parent.

11818 concurrent tagged type prefix should yield a primitive operation.
11819 (Find_Primitive_Operation): Handle case of class-wide types.
11820 (Analyze_Overloaded_Selected_Component): If type of prefix is
11821 class-wide, use visible components of base type.

11823 (Try_Primitive_Operation, Collect_Generic_Type_Ops): If the type is a
11824 formal of a generic subprogram. find candidate interpretations by
11825 scanning the list of generic formal declarations.:
11826 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
11827 type from a limited_with_clause, and the full view is available, use it
11828 for subsequent semantic checks.
11829 (Check_Misspelled_Selector): Use Namet.Sp.Is_Bad_Spelling_Of function
11830 (Find_Primitive_Operation): New function.
11831 (Analyze_Overloaded_Selected_Component): insert explicit dereference
11832 only once if several interpretations of the prefix yield an access type.
11833 (Try_Object_Operation): Code and comment cleanup.
11834 (Analyze_Selected_Component): Reorder local variables. Minot comment and
11835 code reformatting. When the type of the prefix is tagged concurrent, a
11836 correct interpretation might be available in the primitive and
11837 class-wide operations of the type.

11844 frozen.
11845 (Use_One_Type): The clause is legal on an access type whose designated

11849 (Analyze_Renamed_Primitive_Operation): new procedure to determine the
11850 operation denoted by a selected component.
11851 (Analyze_Renamed_Entry): Resolve the prefix of the entry name, because
11852 it can be an expression, possibly overloaded, that returns a task or
11853 an access to one.

11857
11858 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
11859 requeue statement is dispatching. Do not emit an error when the name is
11860 not an entry and the context is a dispatching select. Add code to
11861 perform subtype conformance between the formals of the current entry
11862 and those of the target interface primitive.
11863 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
11864 Timed_Entry_Call): Analyze the triggering statement as the first step of
11865 the processing. If this is a dispatching select, postpone the analysis
11866 of all select statements until the Expander transforms the select. This
11867 approach avoids generating duplicate identifiers after the Expander has
11868 replicated some of the select statements. In case the Expander is
11869 disabled, perform regular analysis.
11870 (Check_Triggering_Statement): New routine.
11871 (Analyze_Requeue): Exclude any interpretations that are not entries when
11872 checking overloaded names in a requeue. Also test type conformance for
11873 matching interpretations rather than requiring subtype conformance at
11874 that point to conform with the RM's resolution rule for requeues.

11878 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
11879 inherited operation is a defaulted tag-indeterminate call, and there is
11880 a statically tagged actual, use the static tag as a controlling actual
11881 for the defaulted actual.

11902 to Related_Type.
11903 (Collect_Interfaces_Info): Minor update to handle the two secondary

11905 (Generate_Parent_Ref): Add parameter to specify entity to check
11906 (Is_Preelaborable_Expression): Allow the name of a discriminant to
11907 initialize a component of a type with preelaborable initialization.
11908 This includes the case of a discriminal used in such a context.
11909 (Is_Dependent_Component_Of_Mutable_Object): Take into account the
11910 latest Ada 2005 rules about renaming and 'Access of
11911 discriminant-dependent components.
11912 (Check_Nested_Access): Add handling when there are no enclosing
11913 subprograms (e.g. case of a package body).

12481 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
12482 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
12483 care of access to class-wide interface types plus removal of bizarre
12484 conversion of tagged object to access type (reported by Gary
12485 Dismukes). After this patch there is no need to perform any
12486 additional management on these nodes in Expand_Interface_Actuals.
12487
12488 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
12489 that handles use of 'Access and 'Unchecked_Access applied to

12535 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info

12581 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
12582 association for an access component, add an association with null as
12583 the expression. Remove testing for array subtypes and the setting in
12584 that case of Ctyp to the array component type, which prevented proper
12585 inclusion of an association for null-initialized arrays. Collapse
12586 condition that tests for array subtypes into just a test of
12587 Is_Partially_Initialized_Type (which already covers arrays anyway).

12907 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
12908 the case where processing continues.
12909 (Expand_Call): If the call is generated from a thunk body then we

12911 level of the access type actuals.
12912
12913 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field

12962 avoids calling Time_Of and Split, thus making it more efficent.
12963 (Week_In_Year): Reimplemented in oder to follow ISO 8601.

12970 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
12971 Command_Line): New types
12972 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
12973 support for defining how switches can be grouped on a command line (as
12974 is the case for -gnatw... for GNAT), and how simple switches can be
12975 used as aliases for more complex switches (-gnatwa is same as
12976 -gnatwbcef...)
12977 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
12978 (Start, Current_*): New subprograms
12979 Added support for parsing an array of strings in addition to the real
12980 command line.
12981 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
12982 be moved from the body to the private part of the spec.
12983 (*): All subprograms now have an extra parameter with default value to
12984 specify which parser should be used. For backward compatibility, it
12985 defaults to parsing the command line of the application. They were also
12986 modified to properly handle cases where each of the argument does not
12987 start at index 1 (which is always true for Ada.Command_Line, but not
12988 when processing any Argument_List).
12989 (Free): New subprogram
12990 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
12991 Argument): New subprograms
12992 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
12993 special characters like ':', '=',... are now handled in a single place,
12994 which makes the code more extensible eventually.
12995 (Getopt, Full_Switch): When the switch was returned as part of the
12996 special character '*', make sure it is prepended by the switch character
12997 ('-' in general), so that the application knows whether "foo" or "-foo"
12998 was specified on the command line.

13011 subprogram and the names of the binder generated files will be derived
13012 from the first ALI file name.

13393 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
13394 create an abstract subprogram in the case of 'Input. For 'Output we now
13395 create a real spec/body when the type is abstract, since it can
13396 potentially be called.
13397 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
13398 body for 'Output when the type is abstract (only the creation of the
13399 body for 'Input is excluded when the type is abstract).
13400 (Stream_Operation_OK): Add an additional condition in the return
13401 statement, so that False will be returned for TTS_Stream_Input if the
13402 associated tagged type is an abstract extension. Add comments for
13403 return statement.
13404 (Expand_N_Object_Declaration): For the case of a shared passive
13405 variable, insert init proc call only after the shared variable
13406 procedures have been processed, because the IP call needs to undergo
13407 shared passive variable reference expansion, which requires these
13408 procedures to be available (and elaborated).

13420 type, retrieve its value from the aggregate itself, where it must have
13421 been supplied.
13422
13423 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
13424 to remove other spurious ambiguities on arithmetic operations involving
13425 literals and addresses, on systems where Address is a visible integer
13426 type, when the operator is called in functional notation.
13427 (Try_Primitive_Operation): Within an instance, a call in prefixed form
13428 is legal when the types match, even if the operation is currently
13429 hidden.

13645 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
13646 flag, for effiency. It is called when analyzing arithmetic operators
13647 and also for actuals in calls that are universal_integers. The flag is
13648 set for the predefined type address, and for any type or subtype
13649 derived from it.
13650
13651 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
13652 Universal_Integer, when the formal is a descendent of address and the
13653 call appears in user code.
13654 (Analyze_Selected_Component): if the prefix is a private extension, the
13655 tag component is visible.

13747
13748 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
13749 ancestor part given by an aggregate to test for an unchecked conversion,
13750 since this can occur in some cases when the ancestor part is a function
13751 call, and we don't want to fall into the recursive call to this
13752 procedure in that case.
13753
13754 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
13755 stream attributes on limited types to account for user-specified
13756 attributes as well as whether Input (resp. Output) becomes available
13757 due to Read (resp. Write) being available for the type. Change Boolean
13758 variable to the more accurate name
13759 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
13760 double-"not" predicate at beginning of return statement to more
13761 understandable form.
13762
13763 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
13764 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
13765 in a block statement and use that as the first statement of the
13766 expanded return rather than incorrectly using the handled sequence as
13767 the first statement.
13768
13769 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
13770 operation, generate an explicit freeze node for it rather than
13771 generating extra formals, to ensure that gigi has the proper order of
13772 elaboration for anonymous subtypes in the signature of the subprograms.
13773 (Build_In_Place_Formal): Move assertion to beginning of loop.
13774 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

13781 and 'Read call.
13782
13783 * freeze.adb (Freeze_Record_Type): Extend the current management of
13784 components that are access type with an allocator as default value: add
13785 missing support to the use of qualified expressions of the
13786 allocator (which also cause freezing of the designated type!)
13787 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
13788 dispatching operation, since extra formals may be needed by calls to
13789 build-in-place functions (such as stream 'Input).
13790
13791 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
13792 formals for 'Constrained and accessibility level in the case of a
13793 predefined dispatching operation.

13806 is not really required and can introduce regression with the debugger.

13822 parameter Including_Non_Switch, defaulted to True. When
13823 Including_Non_Switch is False, options that are not switches and
13824 appear as relative path are not converted to absolute paths.

13839 from the immediate ancestor of Main_Unit_Entity.
13840 (Install_Limited_Withed_Unit): Do not install the limited view of

13877 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
13878 the statement which is being resolved comes from a predefined library
13879 unit, all non-predefined library interpretations are skipped.
13880 (Resolve_Op_Concat): If string concatenation was folded in the parser,
13881 but the "&" is user defined, give an error, because the folding would
13882 be wrong.
13883
13884 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that

13944 needed for access to concurrent record types generated by the expander.
13945 (Generate_Range_Check): When generating a temporary to capture the
13946 value of a conversion that requires a range check, set the type of the
13947 temporary before rewriting the node, so that the type is always
13948 properly placed for back-end use.
13949 (Apply_Float_Conversion_Check): Handle case where the conversion is

13968 parameters when deciding whether to apply a run-time accessibility
13969 check.
13970 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
13971 aggregate code before allocator, and ahead of declaration for
13972 temporary, to prevent access before elaboration when the allocator is
13973 an actual for an access parameter.
13974 (Expand_N_Type_Conversion): On an access type conversion involving an
13975 access parameter, do not apply an accessibility check when the
13976 operand's original node was an attribute other than 'Access. We now
13977 create access conversions for the expansion of 'Unchecked_Access and
13978 'Unrestricted_Access in certain cases and clearly accessibility should
13979 not be checked for those.
13980
13981 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
13982 includes a type conversion of a packed component that has been expanded,
13983 recover the original expression for the object, and use this expression
13984 in the post-call assignment statement, so that the assignment is made
13985 to the object and not to a back-end temporary.
13986 (Freeze_Subprogram): In case of primitives of tagged types not defined
13987 at the library level force generation of code to register the primitive
13988 in the dispatch table. In addition some code reorganization has been
13989 done to leave the implementation clear.
13990 (Expand_Call): When expanding an inherited implicit conversion,
13991 preserve the type of the inherited function after the intrinsic
13992 operation has been expanded.
13993
13994 * exp_ch2.ads, exp_ch2.adb
13995 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
13996 of an entry formal appearing in an assignment statement does not assign
13997 to the formal.
13998 (Expand_Current_Value): Instead of calling a routine to determine
13999 whether the prefix of an attribute reference should be optimized or
14000 not, prevent the optimization of such prefixes all together.
14001
14002 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
14003 component whose prefix is known to be of an access type is an implicit

14013 (Array_Aggr_Subtype): Associate each itype created for an index type to
14014 the corresponding range construct, and not to the aggregate itself. to
14015 maintain a one-to-one correspondence between itype and its associated
14016 node, to prevent errors when complex expression is copied.
14017 Fix mishandling of multiple levels of parens
14018
14019 * sem_aggr.adb: Create a limited view of an incomplete type, to make
14020 treatment of limited views uniform for all visible declarations in a
14021 limited_withed package.
14022 (New_Copy_Tree): If hash table is being used and itype is visited,
14023 make an entry into table to link associated node and new itype.
14024 (Resolve_Record_Aggregate): Do not add an others box association for a
14025 discriminated record component that has only discriminants, when there
14026 is a box association for the component itself.

14065
14066 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
14067 to make treatment of limited views uniform for all visible declarations
14068 in a limited_withed package.
14069 Improve warnings for in out parameters
14070 (Set_Related_Interaface/Related_Interface): Allow the use of this
14071 attribute with constants.
14072 (Write_Field26_Name): Handle attribute Related_Interface in constants.
14073 Warn on duplicate pragma Preelaborable_Initialialization
14074
14075 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
14076 generation of a freezing node to ensure proper management of null
14077 excluding access types in the backend.
14078 (Create_Extra_Formals): Test base type of the formal when checking for
14079 the need to add an extra accessibility-level formal. Pass the entity E
14080 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
14081 originally being done in a couple of cases), to ensure that the
14082 Extra_Formals list gets set on the entity E when the first entity is
14083 added.
14084 (Conforming_Types): Add missing calls to Base_Type to the code that
14085 handles anonymous access types. This is required to handle the
14086 general case because Process_Formals builds internal subtype entities
14087 to handle null-excluding access types.
14088 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
14089 functions that need it, even when not marked Requires_Overriding.
14090 Improve warnings for in out parameters
14091 (Analyze_Function_Return): Warn for disallowed null return
14092 Warn on return from procedure with unset out parameter
14093 Ensure consistent use of # in error messages
14094 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
14095 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
14096 the implicit conversion of the expression done for anonymous access
14097 types. This is required to generate the code of the null excluding
14098 check (if required).
14099
14100 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
14101 A formal parameter is never publicly referenceable outside of its body.
14102 (Check_References): For an unreferenced formal parameter in an accept
14103 statement, use the same warning circuitry as for subprogram formal
14104 parameters.
14105 (Warn_On_Unreferenced_Entity): New subprogram, taken from
14106 Output_Unreferenced_Messages, containing the part of that routine that
14107 is now reused for entry formals as described above.
14108 (Goto_Spec_Entity): New function
14109 (Check_References): Do not give IN OUT warning for dispatching operation
14110 Improve warnings for in out parameters
14111 (Test_Ref): Check that the entity is not undefinite before calling
14112 Scope_Within, in order to avoid infinite loops.
14113 Warn on return from procedure with unset out parameter
14114 Improved warnings for unused variables

14119
14120 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
14121 (Expand_N_Attribute_Reference): Further unify the handling of the
14122 three forms of access attributes, using common code now for all three
14123 cases. Add a test for the case of applying an access attribute to
14124 an explicit dereference when the context is an access-to-interface
14125 type. In that case we need to apply the conversion to the prefix
14126 of the explicit dereference rather than the prefix of the attribute.
14127 (Attribute_Version, UET_Address): Set entity as internal to ensure
14128 proper dg output of implicit importation.
14129 (Expand_Access_To_Type): Removed.
14130 (Expand_N_Attribute_Reference): Merge the code from the three cases
14131 of access attributes, since the processing is largely identical for
14132 these cases. The substantive fix here is to process the case of a
14133 type name prefix (current instance case) before handling the case
14134 of interface prefixes.

14140
14141 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
14142 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
14143 type that is an anonymous access to controlled object, establish
14144 an associated finalization chain to avoid corrupting the global
14145 finalization list when a dynamically allocated object designated
14146 by such a component is deallocated.
14147 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
14148 functions that need it, even when not marked Requires_Overriding.
14149 (Initialize_Tag): Replace call to has_discriminants by call to
14150 Is_Variable_Size_Record in the circuitry that handles the
14151 initialization of secondary tags.
14152 (Is_Variable_Size_Record): New implementation.
14153 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
14154 Suppress_Initialization pragma for a derived type.
14155 (Is_Variable_Size_Record): New subprogram.
14156 (Build_Offset_To_Top_Functions): New implementation that simplifies the
14157 initial version of this routine and also fixes problems causing
14158 incomplete initialization of the table of interfaces.
14159 (Build_Init_Procedure): Improve the generation of code to initialize the
14160 the tag components of secondary dispatch tables.
14161 (Init_Secondary_Tags): New implementation that simplifies the previous
14162 version of this routine.
14163 (Make_DT): Add parameter to indicate when type has been frozen by an
14164 object declaration, for diagnostic purposes.
14165 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
14166 diagnose attemps to freeze a subprogram when some untagged type of its
14167 profile is a private type whose full view has not been analyzed yet.
14168 (Freeze_Array_Type): Generate init proc for packed array if either
14169 Initialize or Normalize_Scalars is set.
14170 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
14171 constructing the new profile, copy the null_exclusion indicator for each
14172 parameter, to ensure full conformance of the new body with the spec.
14173
14174 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
14175 Create wrappers for constructor functions that need it, even when not
14176 marked Requires_Overriding.
14177 (Covers): Handle properly designated types of anonymous access types,
14178 whose non-limited views are themselves incomplete types.
14179 (Add_Entry): Use an entity to store the abstract operation which hides
14180 an interpretation.
14181 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
14182 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
14183 initialization aggregate.
14184 (Function_Interp_May_Be_Hidden): Rename to
14185 Function_Interp_Has_Abstract_Op.
14186 (Has_Compatible_Type): Remove machinery that skips interpretations if
14187 they are labeled as potentially hidden by an abstract operator.
14188 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
14189 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
14190 (Write_Overloads): Output the abstract operator if present.
14191 (Add_Entry): Before inserting a new entry into the interpretation table
14192 for a node, determine whether the entry will be disabled by an abstract
14193 operator.
14194 (Binary_Op_Interp_May_Be_Hidden): New routine.
14195 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
14196 aggregate.
14197 (Function_Interp_May_Be_Hidden): New routine.
14198 (Has_Compatible_Type): Do not consider interpretations hidden by
14199 abstract operators when trying to determine whether two types are
14200 compatible.
14201 (Has_Hidden_Interp): New routine.

14210 the proper body of a stub.
14211 (Set_All_DT_Position): Add missing check to avoid wrong assignation
14212 of the same dispatch table slot to renamed primitives.
14213 (Make_Select_Specific_Data_Table): Handle private types.
14214 (Tagged_Kind): Handle private types.
14215 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
14216 output of implicit importation and exportation.
14217 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
14218 first formal of the thunk is always associated with the controlling
14219 type. In addition perform the following code cleanup: remove formal
14220 Thunk_Alias which is no longer required, cleanup evaluation of the
14221 the controlling type, and update the documentation.
14222 Replace occurrence of Default_Prim_Op_Count by
14223 Max_Predef_Prims. Addition of compile-time check to verify
14224 that the value of Max_Predef_Prims is correct.
14225 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
14226 (Make_DT): Add parameter to indicate when type has been frozen by an
14227 object declaration, for diagnostic purposes.
14228 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
14229 construction of statically allocated dispatch tables.
14230 (Make_DT): In case of library-level tagged types export the declaration
14231 of the primary tag. Remove generation of tags (now done by Make_Tags).
14232 Additional modifications to handle non-static generation of dispatch
14233 tables. Take care of building tables for asynchronous interface types
14234 (Make_Tags): New subprogram that generates the entities associated with
14235 the primary and secondary tags of Typ and fills the contents of Access_
14236 Disp_Table. In case of library-level tagged types imports the forward
14237 declaration of the primary tag that will be declared later by Make_DT.
14238 (Expand_Interface_Conversion): In case of access types to interfaces
14239 replace an itype declaration by an explicit type declaration to avoid
14240 problems associated with the scope of such itype in transient blocks.

14245
9e81dbc7 14246 * exp_util.ads, exp_util.adb:
ab6328d0
AC		 14247 This patch replaces a number of occurrences of explicit tests for N_Null
14248 with calls to Known_Null. This improves tracking of null values, since
14249 Known_Null also catches null constants, and variables currently known to
14250 be null, so we get better tracking.
14251 (Ensure_Defined): create an itype reference only in the scope of the
14252 itype.
14253 (Side_Effect_Free): A selected component of an access type that
14254 denotes a component with a rep clause must be treated as not
14255 side-effect free, because if it is part of a linked structure its
14256 value may be affected by a renaming.
14257 (Expand_Subtype_From_Expr): For limited objects initialized with build
14258 in place function calls, do nothing; otherwise we prematurely introduce
14259 an N_Reference node in the expression initializing the object, which
14260 breaks the circuitry that detects and adds the additional arguments to
14261 the called function. Bug found working in the new patch for statically
14262 allocated dispatch tables.
14263 (Is_Library_Level_Tagged_Type): New subprogram.
14264 (Remove_Side_Effects): If the expression of an elementary type is an
14265 operator treat as a function call.
14266 (Make_Literal_Range): If the index type of the array is not integer, use
14267 attributes properly to compute the constraint on the resulting aggregate
14268 which is a string.
14269
14270 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
14271 class-wide type whose base type is an incomplete private type, leave
14272 class-wide type unfrozen so that freeze nodes can be generated
14273 properly at a later point.
14274 (Freeze_Entity, array case): Handle case of pragma Pack and component
14275 size attributre clause for same array.
14276

14902 of Set_Item.
14903 (Set_Item): When the new item is an element of the currently allocated
14904 table passed by reference, save a copy on the stack if we're going
14905 to reallocate. Also, in Table.Set_Item, make sure we test the proper
14906 variable to determine whether to call Set_Last.

14921 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
14922 derived type with interface progenitors use the analyzed formal as the
14923 parent of the actual, to create renamings for all the inherited
14924 operations in Derive_Subprograms.
14925 (Collect_Previous_Instances): new procedure within of
14926 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
14927 unit being loaded, to ensure that the generation of global symbols is
14928 consistent in different compilation modes.
14929 (Is_Tagged_Ancestor): New function testing the ancestor relation that
14930 takes progenitor types into account.
14931 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
14932 traversing over the primitives of the formal and actual types to locate
14933 any abstract subprograms of the actual type that correspond to a
14934 nonabstract subprogram of the formal type's ancestor type(s), and issue
14935 an error if such is found.
14936 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
14937 Instantiate_Package_Body, Instantiate_Subprogram_Body):
14938 Remove bogus guard around calls to Inherit_Context.

14940 that denotes a named number, propagate constant-folding to the generic
14941 template only if the named number is global to the generic unit.
14942 (Set_Instance_Env): Only reset the compilation switches when compiling
14943 a predefined or internal unit.

149452007-08-14 Ed Schonberg <schonberg@adacore.com>
14946
14947 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
14948 parameter to determine whether operation applies to the prefix.
14949 (Complete_Object_Operation): If actual has an access type and
14950 controlling formal is not an in_parameter, reject the actual if it is
14951 an access_to_constant type.
14952 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
14953 type, the candidate operations are found in the scope of declaration of
14954 the type, because the type has no primitive subprograms.
14955 (Analyze_Selected_Component): If prefix is class-wide, and root type is
14956 a private extension, only examine visible components before trying to
14957 analyze as a prefixed call.
14958 Change Entity_List to Type_To_Use, for better readability.
14959 (Has_Fixed_Op): Use base type when checking whether the type of an

14968 formal At_Any_Place indicating, when True, that we want to test for
14969 availability of the stream attribute at any place (as opposed to the
14970 current visibility context only).
14971 (Missing_Read_Write_Attributes): A stream attribute is missing for the
14972 purpose of enforcing E.2.2(8) only if it is not available at any place.
14973 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
14974 when checking the legality of an extension aggregate in a preelaborable
14975 package. Treat the literal null as a valid default expression in a
14976 component declaration for a type with preelaborable initialization.
14977 A limited interface is a legal progenitor for the designated type of a
14978 remote access to class-wide type.

14990 mark the full view as referenced, to prevent spurious warnings.
14991 (Find_Selected_Component, Has_Components): Handle properly non-limited
14992 views that are themselves incomplete types.
14993 Handle interfaces visible through limited-with clauses.

15006 the allocator is not a coextension.
15007 (Resolve): Skip an interpretation hidden by an abstract operator only
15008 when the type of the interpretation matches that of the context.
15009 (Resolve): When looping through all possible interpretations of a node,
15010 do not consider those that are hidden by abstract operators.
15011 (Resolve_Actuals): When verifying that an access to class-wide object
15012 is an actual for a controlling formal, ignore anonymous access to
15013 subprograms whose return type is an access to class_wide type.
15014 (Resolve_Slice): If the prefix of the slice is a selected component
15015 whose type depends on discriminants, build its actual subtype before
15016 applying range checks on the bounds of the slice.
15017 (Valid_Conversion): In an instance or inlined body, compare root types,
15018 to prevent anomalies between private and public views.
15019 (Resolve): Improve error message for ambiguous fixed multiplication
15020 expressions that involve universal_fixed multiplying operations.

15040 elabration statements, register the package with the name server
15041 at the beginning, not at the end, of the elaboration statements so

15253 Add s-osinte-vxworks-kernel.adb to the target pairs of the
15254 kernel run-time lib for VxWorks 6, which would provide a different
15255 implementation for Task_Cont and Task_Stop than the VxWorks 5 version.
15256 x86-solaris section (EH_MECHANISM): Set to -gcc, as this port is now
15257 running ZCX by default.

16093 * utils2.c (build_allocator): Provide the extra arguments to
16094 make_aligning_type for super-aligned objects allocated from the default
16095 pool. Leave enough room for a pointer before the aligning field, and
16096 store the system's allocator return value there.
16097 (build_call_alloc_dealloc): When releasing a super-aligned object,
16098 retrieve the system's allocator return value from where build_allocator
16099 has stored it, just ahead of the adjusted address we are passed.
16100 (build_call_raise): Handle properly the generation of line numbers when
16101 the node is marked No_Location.

16132 Zero_Formatting is set.
16133 Add case for CLI_Target.
16134 (System_Restrictions_Used): New flag, used to avoid generating with of
16135 System_Restrictions and initialization of the data unless there is
16136 some use of System.Restrictions in the partition.
16137 (Check_System_Restrictions_Used): New procedure
16138

16157
16158 * checks.ads, checks.adb (Apply_Address_Clause_Check): Handle case in
16159 which the address-clause is applied to in-mode actuals (allowed by
16160 13.1(22)).
16161 (Apply_Discriminant_Check): Do not generate a check if the type is
16162 constrained by a current instance.
16163 (Activate_Division_Check): New procedure
16164 (Activate_Overflow_Check): New procedure
16165 (Activate_Range_Check): New procedure
16166 Call these new Activate procedures instead of setting flags directly
16167 (Apply_Array_Size_Check): Removed, no longer needed.
16168 Code clean up: remove obsolete code related to GCC 2.
16169 (Get_E_Length): Protect against bomb in case scope is standard
16170 (Selected_Range_Checks): If the node to be checked is a conversion to
16171 an unconstrained array type, and the expression is a slice, use the
16172 bounds of the slice to construct the required constraint checks.
16173 Improve NOT NULL error messages
16174 (Apply_Constraint_Check): If the context is a null-excluding access
16175 type, diagnose properly the literal null.
16176
161772007-06-06 Pascal Obry <obry@adacore.com>
16178

16180 and the corresponding .deps file.
16181 (Clean_Interface_Copy_Directory): Use untouched casing for the library

16191 Arnaud Charlet <charlet@adacore.com>
16192
16193 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
16194 applicable to types that have the With_Type flag set. Returns the
16195 non-limited view of the type, if available, otherwise the type itself.
16196 For class-wide types, there is no direct link in the tree, so we have
16197 to retrieve the class-wide type of the non-limited view of the Etype.
16198 New attributes Static_Initialization and Static_Elaboration_Desired.
16199 Remove the pragma Thread_Body, and the associated flag
16200 Is_Thread_Body in entities, and all related code.
16201 (Suppress_Value_Tracking_On_Call): New flag
16202 E_Exception has Esize and Alignment fields
16203 (Universal_Aliasing): New function.

16207 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
16208 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
16209 (Related_Interface): New attribute. Present in dispatch table pointer
16210 components of records. Set to point to the entity of the corresponding
16211 interface type.
16212 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
16213 (Original_Access_Type): Remove, not needed.
16214 (Root_Type): Handle properly subtypes of class-wide-types.
16215 Update comments.
16216
16217 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
16218 class-wide types visible through limited-with clauses.
16219 (Try_Primitive_Operation): When examining all primitive operations of a
16220 tagged type, do not consider subprograms labeled as hidden unless they
16221 belong to a private generic type with a tagged parent.
16222 (Try_Object_Operation): Extensive rewriting, to handle properly various
16223 overloading cases, when several ancestors may have class-wide operations
16224 that are possible candidates, and when the overloaded functions return
16225 array types and have defaulted parameters so that the call may be
16226 interpreted as an indexing.
16227 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
16228 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
16229 successive actuals before analyzing the call itself.
16230 (Try_Primitive_Operation): A primitive operation is compatible with the
16231 prefix if the prefix has a synchronized type and the type of the formal
16232 is its corresponding record, as can be the case when the primitive
16233 operation is declared outside of the body of the type.
16234 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
16235 perform homonym traversal, looking for class-wide operation matches
16236 (formerly done in statements of Try_Class_Wide_Operation). Matches on
16237 access parameters are now restricted to anonymous access types.
16238 (Mark_Allocator): An allocator with a discriminant association parent is
16239 a coextension.
16240 (Try_One_Prefix_Interpretation): If the type of the object is
16241 incomplete, as can be happen when it is a limited view obtained through
16242 a limited_with_clause, the selected component is not part of a prefixed
16243 call.
16244 (Complete_Object_Operation): Diagnose properly an object that is not
16245 aliased when the corresponding controlling formal is an access
16246 parameter.
16247 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
16248 ambiguous calls in prefixed notation, where two primitives differ only
16249 in that the controlling argument of one is an access parameter.
16250
16251 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
16252 whether a function that returns an unconstrained type can be inlined.
16253 (Process_Formals): Diagnose properly the illegal use of an incomplete
16254 type in the profile of an access_to_subprogram declaration.
16255 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
16256 operations are attached to the corresponding record.
16257 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
16258 When processing a primitive of a concurrent type which implements an
16259 interface change the type of all controlling formals to that of the
16260 corresponding record type.
16261 (Check_Synchronized_Overriding): Relax the conditional logic when trying
16262 to determine the tagged type to which a primitive belongs.
16263 (Check_Conventions): Capture condition to ignore a primitive operation
16264 (which is shared between the loop in Check_Conventions and the one in
16265 Check_Convention) in a new local function Skip_Check.
16266 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
16267 confusion with Check_Conventions' own Prim_Op local variable.
16268 (Create_Extra_Formals): Test for a tagged result type rather than a
16269 controlling result when determining whether to add a BIP_Alloc_Form
16270 formal and a BIP_Final_List formal to the function.
16271 (Check_Conformance); For parameters that are anonymous access types,
16272 subtype conformance requires that the not null and the constant
16273 indicators must match
16274 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
16275 to retrieve the appropriate type when processing a concurrent type
16276 declared within a generic. Minor comment reformatting. Change invocation
16277 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
16278 mitive.
16279 (Analyze_Subprogram_Body): If the return type of a function is an
16280 anonymous access to the limited view of a class-wide type, and the
16281 non-limited view of the type is available, update the type of the
16282 function so that code can be generated.
16283 (Process_Formals): In case of access-subtype itype whose designated
16284 type is also an itype (situation that happens now with access to
16285 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
16286 attribute to avoid backend problems.
16287 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
16288 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
16289 anonymous types' designated types are same before testing
16290 Subtypes_Statically_Match.
16291 (Create_Extra_Formals): Test for a named access parameter that is a
16292 controlling formal as an additional condition for adding an
16293 accessibility level formal. This can occur in the subp type created for
16294 dispatching calls in Expand_Dispatching_Call, and allows calling
16295 Create_Extra_Formals from that procedure rather than special-casing the
16296 extra formals there.
16297 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
16298 when the function has a controlling result.
16299 (Check_Returns): Add much more knowledge of the optimization of local
16300 raise statements to gotos, to retain proper warnings in this case.
16301 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
16302 nodes when looking for last statement.
16303
16304 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
16305 class-wide types visible through limited with clauses.
16306 (Add_One_Interp): If the operands are anonymous access types, the
16307 predefined operator on universal_access is immediately visibles
16308 (Find_Unique_Type): Handle anonymous access to subprogram types just as
16309 other anonymous access types.
16310 (Disambiguate): Take into account CIL convention.
16311 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
16312
163132007-06-06 Robert Dewar <dewar@adacore.com>
16314
16315 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
16316 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
16317 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
16318 Fix lower bound of tables.
16319 Add rep clauses.
16320
16321 * nlists.adb: Ditto.
16322 (Prev_Node, Next_Node): Change index type to Int so that it properly
16323 covers the range First_Node_Id - 1 up.

9e81dbc7 16330 * exp_aggr.ads, exp_aggr.adb:
ec11296f
AC		 16331 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
16332 in extension aggregates.
16333 (Flatten): Other conditions being met, an aggregate is static if the
16334 low bound given by component associations is different from the low
16335 bound of the base index type.
16336 (Packed_Array_Aggregate_Handled): If the component type is itself a
16337 packed array or record, the front-end must expand into assignments.
16338 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
16339 Init_Pr, instead of Ancestor_Is_Expression.
16340 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
16341 coextension chain root, either generate a list controller or use the
16342 already existing one.
16343 (Static_Array_Aggregate): New procedure to construct a positional
16344 aggregate that can be handled by the backend, when all bounds and
16345 components are compile-time known constants.
16346 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
16347 types covering interface types into assignments.
16348 (Replace_Type): move to Build_Record_Aggr_Code.
16349 (Expand_Record_Aggr_Code): if the target of the aggregate is an
16350 interface type, convert to the definite type of the aggregate itself,
16351 so that needed components are visible.
16352 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
16353 components and the context is an extended return statement do not
16354 create a transient block for it, to prevent premature finalization
16355 before the return is executed.
16356 (Gen_Assign): Do not generate a call to deep adjust routine if the
16357 component type is itself an array of controlled (sub)-components
16358 initialized with an inner aggregate.
16359 (Component_Check): New name for Static_Check. This name is now more
16360 appropriate, and documentation is added which was missing.
16361 (Component_Check): Add test for bit aligned component value
16362 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
16363 Tagged_Comps, name is more appropriate given added function below.
16364 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

16368 Robert Dewar <dewar@adacore.com>
16369
16370 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
16371 Terminated: Add unchecked type conversion from System.Address to
16372 System.Tasking.Task_Id when calling the predefined primitive
16373 _disp_get_task_id.
16374 Disable new Ada 05 accessibility check for JVM.NET targets, which
16375 cannot be implemented in a practical way.
16376 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
16377 the sources always references the tag of the actual object. Therefore,
16378 if 'Tag is applied in the sources to class-wide interface objects we
16379 generate code that displaces "this" to reference the base of the object.
16380 (Expand_N_Attribute_Reference, case Size): Return specified size if
16381 known to front end.
16382 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
16383 has code that displaces the pointer of the object to manage interface
16384 types. However this code must not be executed when the prefix is a
16385 subprogram. This bug caused the wrong expansion of the internally
16386 generated assignment that fills the dispatch table when the primitive
16387 is a function returning a class-wide interface type.
16388 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
16389 Set_Attribute_Name for Name_Unaligned_Valid.

16396 procedure of the type, do not remove it.
16397 (Expand_N_Attribute_Definition_Clause): Exclude access variables
16398 initialized to null from having their expression reset to empty and
16399 note this exception in the comment.

16409 references where the prefix must be a simple name.
16410
16411 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
16412 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
16413 Attribute_Requires_Simple_Name_Prefix.
16414 (Name_Modifies_Prefix): Body of new function.
16415 (Requires_Simple_Name_Prefix): Body of new function.
16416 (Resolve_Attribute, case Access): Improve error message for case of
16417 mismatched conventions.
16418 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
16419 incomplete type.
16420 (Analyze_Attribute, case 'Access): If the type of the prefix is a
16421 constrained subtype for a nominal unconstrained type, use its base type
16422 to check for conformance with the context.
16423 (Resolve_Attribute): Remove test of the access type being associated
16424 with a return statement from condition for performing accessibility
16425 checks on access attributes, since this case is now captured by
16426 Is_Local_Anonymous_Access.
16427 (Analyze_Access_Attribute): Set Address_Taken on entity
16428 (Analyze_Attribute, case Address): Set Address_Taken on entity
16429 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
16430 validating an access attribute whose prefix is a current instance.
16431 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
16432 applied to dispatching operations, if freezing is required then we set
16433 the attribute Has_Delayed_Freeze in the prefix's entity.
16434 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
16435 current scope if access of local subprogram taken
16436 (Analyze_Access_Attribute): Check legality of self-reference even if the
16437 expression comes from source, as when a single component association in
16438 an aggregate has a box association.
16439 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
16440 the prefix if it is a protected operation and the attribute is
16441 Unrestricted_Access.
16442 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
16443 reference to the base type of the context, to force a constraint check
16444 when the context is an access subtype with an explicit constraint.
16445 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
16446 node is rewritten as an interface conversion. leave unanalyzed after
16447 resolution, to ensure that type checking against the context will take
16448 place.

16451 Javier Miranda <miranda@adacore.com>
16452 Robert Dewar <dewar@adacore.com>
16453
16454 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
16455 wrapper when the full view of the controlling type of an inherited
16456 function that dispatches on result implements interfaces.
16457 (Expand_N_Object_Declaration): In cases where the type of the
16458 declaration is anonymous access, create finalization list for it.
16459 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
16460 if the object has no explicit initialization, to match description of
16461 functionality of pragam Persistent_BSS.
16462 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
16463 new function to build static aggregates, to replace initialization call
16464 when static initialization is desired.
16465 (Freeze_Type): Generate a list controller for an access type whenever
16466 its designated type has controlled anonymous access discriminants.
16467 (Build_Equivalent_Aggregate): New procedure to compute a static
16468 aggregate to be used as default initialization for composite types,
16469 instead of a generating a call to the initialization procedure for the
16470 type.
16471 (Build_Initialization_Call): When available, replace a call to the
16472 initialization procedure with a copy of the equivalent static aggregate
16473 for the type.
16474 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
16475 declarations for objects of a class-wide interface type, rather than
16476 just identifiers, to prevent visibility problems.
16477 (Expand_N_Object_Declaration): When expanding the declaration for an
16478 object of a class-wide interface type, preserve the homonym chain of
16479 the original entity before exchanging it with that of the generated
16480 renaming declaration.
16481 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
16482 active, because there is no way to handle the exception.
16483 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
16484 to do a minimum decoration of the Access_Disp_Table list.
16485 (Expand_Record_Controller): Avoid the addition of the controller between
16486 the component containing the tag of a secondary dispatch table and its
16487 adjacent component that stores the offset to the base of the object.
16488 This latter component is only generated when the parent type has
16489 discriminants ---documented in Add_Interface_Tag_Components).
16490 (Apply_Array_Size_Check): Removed, no longer needed.
16491 (Expand_N_Full_Type_Declaration): If the type has anonymous access
16492 components, create a Master_Entity for it only if it contains tasks.
16493 (Build_Init_Procedure): Suppress the tag assignment compiling under
16494 no run-time mode.
16495 (Freeze_Record_Type): Remove code associated with creation of dispatch
16496 table.
16497 (Init_Secondary_Tags): Update type of actuals when generating calls to
16498 Ada.Tags.Set_Offset_To_Top
16499 (Stream_Operation_OK): Disable use of streams compiling under no
16500 run-time mode
16501 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
16502 if Has_Init_Expression set.
16503 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
16504 Register_Primitive, which provides the same functionality.
16505 (Requires_Init_Proc): Return false in case of interface types.
16506 (Add_Secondary_Tables): Use the new attribute Related_Interface to
16507 cleanup the code.
16508 (Predefined_Primitive_Freeze): Do not assume that an internal entity
16509 is always associated with a predefined primitive because the internal
16510 entities associated with interface types are not predefined primitives.
16511 Therefore, the call to Is_Internal is replaced by a call to the
16512 function Is_Predefined_Dispatching_Operation.
16513 (Make_Eq_If): When generating the list of comparisons for the
16514 components of a given variant, omit the controller component that is
16515 present if the variant has controlled components.

16519 Bob Duff <duff@adacore.com>
16520
16521 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
16522 handle the creation of finalization lists and calls for nested
16523 coextensions when the root of the chains is part of a return statement.
16524 (Inside_A_Return_Statement): New function inside Complete_Coextension_
16525 Finalization.
16526 (Expand_Record_Equality): Skip components that are interface types.
16527 (Displace_Allocator_Pointer): Add missing support for interface subtypes
16528 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
16529 with Rewrite_Coextension. Change the condition for detecting coextension
16530 root nodes.
16531 (Is_Local_Access_Discriminant): Removed.
16532 (Rewrite_Coextension): New routine which rewrites a static coextension
16533 as a temporary and uses its unrestricted access in the construction of
16534 the outer object.
16535 (Complete_Coextension_Finalization): New routine. Generate finalization
16536 attachment calls to all delayed coextensions.
16537 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
16538 the allocator is not a coextension itself and has delayed coextensions.
16539 If the current allocator is controlled, but also a coextension, delay
16540 the generation of the finalization attachment call.
16541 Rename local variable "Node" to "Nod" in order to avoid confusion with
16542 "Elists.Node".
16543 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
16544 limited types that are not inherently limited. Such an allocator is
16545 illegal, but is generated by the expander for a return statement, to
16546 copy the result onto the secondary stack. This is the only case where a
16547 limited object can be copied. Generate code to displace the pointer
16548 to the object if the qualified expression is a class-wide interface
16549 object. Such displacement was missing and hence the copy of the object
16550 was wrong.
16551 (Apply_Accessibility_Check): Handle allocated objects initialized in
16552 place.
16553 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
16554 and Expand_Allocator_Expression. Allocating class-wide interface objects
16555 this routine displaces the pointer to the allocated object to reference
16556 the component referencing the corresponding secondary dispatch table.
16557 Expand_Allocator_Expression): Add missing support to allocate class-wide
16558 interface objects initialized with a qualified expression.
16559 (Get_Allocator_Final_List): Test for an anonymous access type that is a
16560 function result type, and use the finalization list associated with the
16561 function scope in that case (such an anonymous type should not be
16562 treated like an access parameter's type).
16563
165642007-06-06 Ed Schonberg <schonberg@adacore.com>
16565 Gary Dismukes <dismukes@adacore.com>
16566 Javier Miranda <miranda@adacore.com>
16567
16568 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
16569 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
16570 required exception handler.
16571 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
16572 properly the case of a function whose return type is a limited
16573 class-wide interface type. Modify the code of the accessibility
16574 check to handle class-wide interface objects. In this case we need to
16575 displace "this" to reference the primary dispatch table to get access
16576 to the TSD of the object (to evaluate its accessibility level).
16577 (Expand_N_Extended_Return_Statement): Test for a tagged result type
16578 rather than a controlling result as one of the conditions for
16579 generating tests of the implicit BIP_Alloc_Form formal. The
16580 initialization assignment is also handled according to whether the
16581 result is tagged instead of controlling.
16582 In the case where the init assignment is inserted in the "then" part of
16583 the allocation conditional, rewrite the target to be a dereference of
16584 the implicit BIP_Object_Access formal.
16585 If the returned value is unconstrained and created on the secondary
16586 stack, mark the enclosing block and function so that the secondary
16587 stack is not reclaimed on return.
16588 Treat returns from functions with controlling results similarly to
16589 returns from functions with unconstrained result subtypes.
16590 If the object returned is unconstrained, and an allocator must be
16591 created for it, analyze the allocator once the block for the extended
16592 return is installed, to ensure that finalizable components
16593 of the expression use the proper finalization list. Guard the call to
16594 Move_Final_List with a check that there is something to finalize.
16595 (Make_Tag_Ctrl_Assignment): Use "old" handling
16596 of controlled type assignment for virtual machines, since new code uses
16597 unsupported features (such as direct access to bytes in memory).
16598
165992007-06-06 Gary Dismukes <dismukes@adacore.com>
16600 Ed Schonberg <schonberg@adacore.com>
16601
16602 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
16603 accessibility actual, check for the case of an aliased object that has
16604 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
16605 we fall into processing for the attribute rather than the name of the
16606 object.
16607 (Expand_Inline_Call): If an actual is a literal, and the corresponding
16608 formal has its address taken in the body, create a temporary to capture
16609 value. If the return type is a limited interface, do not treat the
16610 return value as Controlled.
16611 (Is_In_Place_Function): If the return type is a limited interface,
16612 treat as returning in place. The actual returned object may not always
16613 be limited, but the caller has to assume that it is returned in place.
16614 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
16615 context of an allocator, use the correct finalization chain (that is,
16616 the chain belonging to the access type, rather than the chain belonging
16617 to the current scope).
16618 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
16619 result type rather than a controlling result as a precondition for
16620 adding an allocation form actual to a build-in-place call.
16621 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
16622 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
16623 primitive in the dispatch tables. This work is now done by Make_DT when
16624 the type is frozen.
16625 (Register_Predefined_DT_Entry): Removed.
16626 (Add_Return): If end label is not present, use sloc of last statement
16627 for generated return statement in procedure, for better gdb behavior
16628 on expanded code.
16629 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
16630 object address nodes to ensure proper processing by routines like
16631 Insert_After*.
16632 (Expand_Call): Fix generation of validity check for parameter
16633 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
16634 the allocation form parameter if the result subtype is constrained,
16635 except when the function has a controlling result.
16636 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
16637 rather than Is_Controlled and Has_Controlled_Component, since we want to
16638 include class-wide result types in this treatment. Also test for a
16639 controlling result, since that also requires passing a finalization
16640 list.
16641 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
16642 even when the result subtype is constrained, to handle calls involving
16643 controlling results.
16644 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
16645 is now called even when the result subtype is constrained, to handle
16646 calls involving controlling results.
16647 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
16648 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
16649 now performs the test).
16650 (Make_Build_In_Place_Call_In_Object_Declaration):
16651 Add_Alloc_Form_Actual_* is now called even when the result subtype is
16652 constrained, to handle calls involving controlling results.
16653 (Add_Return): Accomodate rewritten pattern from local raise to goto
16654 transformation, so that we still recognize an transfer statement
16655 and do the right thing here in that case.
16656 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
16657 and end of subprogram code.
16658 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
16659 support for primitives that are functions (without formals) with a
16660 controlling result.
16661 (Inherited_From_Formal): If the actual subtype has not generic parent
16662 type, it is not an actual for a formal derived type, and there is no
16663 operation to inherit from the formal.
16664
166652007-06-06 Ed Schonberg <schonberg@adacore.com>
16666 Thomas Quinot <quinot@adacore.com>
16667
16668 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
16669 inserted cleanup code appropriately for GDB use.
16670 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
16671 exception handler for Deep_Adjust or Deep_Finalize.
16672 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
16673 Raise_From_Controlled_Operation is available, use a call to that
16674 subprogram instead of a plain "raise Program_Error" node to raise
16675 Program_Error if an exception is propagated from an Adjust or Finalize
16676 operation.
16677 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
16678 appears in the optional statement list of a triggering alternative, the
16679 scope actions can be inserted directly there, and not in the list that
16680 includes the asynchronous select itself.
16681

16683 Robert Dewar <dewar@adacore.com>
16684 Hristian Kirtchev <kirtchev@adacore.com>
16685
16686 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
16687 generated exception handler appropriately when debugging generated code.
16688 Deal properly with No_Exception_Propagation restriction mode.
16689 (Expand_N_Abort_Statement): Add an unchecked type conversion from
16690 System.Address to System.Tasking.Task_Id when processing the result of
16691 the predefined primitive _disp_get_task_id.
16692 (Expand_N_Asynchronous_Select): Clarify comment.
16693 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
16694 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
16695 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
16696 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
16697 privals and for generated call to Complete_Entry_Body, for better gdb
16698 behavior.
16699 (Copy_Result_Type): Utility to construct a parameter and result profile
16700 for protected functions whose return type is an anonymous access to
16701 subprogram.
16702 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
16703 call the above.
16704 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
16705 point when the local-raise-to-goto transformation has taken place.
16706
167072007-06-06 Javier Miranda <miranda@adacore.com>
16708 Nicolas Setton <setton@adacore.com>
16709
16710 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
16711 functionality when the backend is generating code.
16712 Otherwise any serious error
16713 reported by the backend calling the frontend routine Error_Msg
16714 changes the Compilation_Mode to Check_Semantics, disables the
16715 functionality of this routine and causes the generation of
16716 spureous additional errors.
16717
16718 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
16719 debugging information now generated by the compiler for fat-pointer
16720 types.
16721 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
16722 DWARF2/3.
16723 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
16724
167252007-06-06 Thomas Quinot <quinot@adacore.com>
16726
16727 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
16728 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16729 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
16730 For a remote call to a function with a classwide return type, apply an
16731 E.4(18) check to the returned value.
16732 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
16733 stream attributes of the designated type of an RACW, as they are not
16734 dispatching primitive operations.
16735
167362007-06-06 Geert Bosch <bosch@adacore.com>
16737
16738 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
16739 negative literal
16740 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
16741 positive
16742 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
16743 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
16744 positive
16745 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
16746
167472007-06-06 Javier Miranda <miranda@adacore.com>
16748
16749 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
16750 attribute compiling package Ada.Tags under No_Run_Time_Mode.
16751
167522007-06-06 Javier Miranda <miranda@adacore.com>
16753
16754 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
16755 deallocation of class-wide interface objects.
16756 (Expand_Dispatching_Constructor_Call): Take into account that if the
16757 result of the dispatching constructor is an interface type, the
16758 function returns a class-wide interface type; otherwise the returned
16759 object would be actual. The frontend previously accepted returning
16760 interface types because Expand_Interface_Actuals silently performed
16761 the management of the returned type "as if" it were a class-wide
16762 interface type.
16763 (Expand_Dispatching_Constructor_Call): Replace call to
16764 Make_DT_Access_Action by direct call to Make_Function_Call.
16765
167662007-06-06 Robert Dewar <dewar@adacore.com>
16767 Ed Schonberg <schonberg@adacore.com>
16768
16769 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
16770 compute masking constant, since we now set Esize properly to the
16771 underlying size.
16772 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
16773 to match the alignment.
16774 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
16775 packed arrays of 8 bits or less.
16776
16777 * freeze.adb (Freeze_Entity): When freezing the formals of a
16778 subprogram, freeze the designated type of a parameter of an access type
16779 only if it is an access parameter.
16780 Increase size of C convention enumeration object
16781 (Freeze_Entity, array type case): Make sure Esize value is properly
16782 adjusted for the alignment if it is known.
16783 (Freeze_Entity, array type case): When checking bit packed arrays for
16784 the size being incorrect, check RM_Size, not Esize.
16785 (Freeze_Record_Type): Check for bad discriminated record convention
16786 (In_Exp_Body): Return true if the body is generated for a subprogram
16787 renaming, either an attribute renaming or a renaming as body.
16788 (Check_Itype): If the designated type of an anonymous access component
16789 is a non-protected subprogram type, indicate that it is frozen, to
16790 prevent out-of-scope freeze node at some subsequent call.
16791 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
16792 only if the subprogram is neither imported nor exported, as well as the
16793 NCA descriptor class if the subprogram is exported.
16794

16799
16800 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
16801 default initialization on an imported object, when there is no
16802 initialization call generated for it.
16803 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
16804 restriction
16805
16806 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
16807 Static_Elaboration_Desired.
16808 Remove pragma Thread_Body.
16809 Implement a new pragma No_Body
16810 Removes the Explicit_Overriding pragma
16811 Remove Optional_Overriding pragma
16812 (Prag): Deal with Universal_Aliasing.
16813 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
16814 Pragma_CIL_Constructor): New names.

17180 to simplify handling of formal interfaces that derive from other formal
17181 interfaces.

17192 declaration, to ensure that the interface list is processed correctly.
17193 (Inline_Instance_Body): If enclosing scope is an instance body, remove

17195 (Pre_Analyze_Actuals): if the actual is an allocator with constraints
17196 given with a named association, analyze the expression only, not the
17197 discriminant association itself.
17198 (Reset_Entity): If the analysis of a selected component is transformed
17199 into an expanded name in the prefix of a call with parameters, do not
17200 transform the original node into an expanded name, to prevent visibility

17202 (Check_Private_View): For an array type, check whether the index types
17203 may need exchanging.

17327 component declaration, when the prefix is an expanded name.
17328 (Inherit_Component): If the derivation is for a private extension,
17329 inherited components remain visible and their ekind should not be set
17330 to Void.
17331 (Find_Type_Of_Object): In the case of an access definition, always set
17332 Is_Local_Anonymous_Access. We were previously not marking the anonymous

17351 improve the condition that avoids inheriting the components associated
17352 with secondary tags of the parent.

17373 * sem_aggr.adb (Resolve_Record_Aggregate): Ignore internal components
17374 of the type that specify the position of interface tags when the type
17375 inherits discriminated array components from the parent type.
17376 If a component is initialized with a box, check for the presence of a
17377 default expression in its declaration before using its default
17378 initialization procedure.
17379 (Resolve_Record_Aggregate): If a component is box-initialized, and the
17380 component type has a discriminants, create a partial aggregate for it
17381 by copying the discriminants of the component subtype.
17382 Reject attempt to initialize a discriminant with a box.
17383 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
17384 associated with dispatch tables is known at compile time.

17386 association, and the corresponding record component has a default
17387 expression, always copy the default expression, even when the

17398 not null indicator.
17399
17400 * par-ch3.adb (P_Known_Discriminant_Part_Opt, P_Component_Items): If
17401 multiple identifier are present, save Scan_State before scanning the
17402 colon, to ensure that separate trees are constructed for each

17405 Has_Init_Expression if initialization expression present.
17406 (P_Null_Exclusion): Properly diagnose NOT NULL coming before NULL

17477 and the full-view.
17478 (Analyze_With_Clause): Improve placement of flag for case of
17479 unimplemented unit.
17480 (Analyze_With_Clause): Recognize use of GNAT.Exception_Traces in a
17481 manner similar to GNAT.Current_Exception. This is a violation of
17482 restriction (No_Exception_Propagation), and also inhibits the
17483 optimization of local raise to goto.
17484 (Analyze_With_Clause): Check for Most_Recent_Exception being with'ed,
17485 and if so set Most_Recent_Exception_Used flag in Opt, and also check

17501 protected type does not implement a task interface or a nonlimited
17502 interface.
17503 (Analyze_Task_Type): Rearrange and simplify code for testing that a task
17504 type does not implement a protected interface or a nonlimited interface.

17509 routines if the expander is not active.
17510 (Analyze_Task_Body): Mark all handlers to stop optimization of local
17511 raise, since special things happen for task exception handlers.

17574 Do_Division_Check flag explicitly.
17575 (Resolve_Actuals): If the actual is of a synchronized type, and the
17576 formal is of the corresponding record type, this is a call to a
17577 primitive operation of the type, that is declared outside of the type;
17578 the actual must be unchecked-converted to the type of the actual
17579 (Resolve_Call): Kill all current values for any subprogram call if
17580 flag Suppress_Value_Tracking_On_Call is set.
17581 (Resolve_Type_Conversion): Generate error message the the operand
17582 or target of interface conversions come from a limited view.
17583 (Check_Infinite_Recursion): Ignore generated calls
17584 (Check_Allocator_Discrim_Accessibility): New procedure for checking
17585 that an expression that constrains an access discriminant in an
17586 allocator does not denote an object with a deeper level than the
17587 allocator's access type.
17588 (Resolve_Allocator): In the case of an allocator initialized by an

17610 overriding of an inherited private subprogram now there is no need to
17611 inherit its dispatching slot and reduce the size of the dispatch table.

17615 of calling Set_All_DT_Position to re-evaluate the position of the
17616 entries in the dispatch table. Such reevaluation is not desired if

17646 (Type_Access_Level): In the case of a type whose parent scope is a
17647 return statement, call Type_Access_Level recursively on the enclosing
17648 function's result type to determine the level of the return object's
17649 type.

18485 (Resolve_Call): If the call returns an array, the context imposes the
18486 component type of the array, and the function has one non-defaulted
18487 parameter, rewrite the call as the indexing of a call with a single
18488 parameter, to handle an Ada 2005 syntactic ambiguity for calls written

18628 (Expand_Inlined_Call): If the subprogram is a null procedure, or a
18629 stubbed procedure with a null body, replace the call with a null
18630 statement without using the full inlining machinery, for efficiency
18631 and to avoid invalid values in source file table entries.
18632
18633 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Add support for
18634 renamings of calls to build-in-place functions.

18652 unit. If this unit has not been loaded, it returns Empty.
18653 (RTE): Addition of a new formal that extends the search to the scopes

18685 Remove no longer used entities.
18686
18687 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

18727 "X'Unrestricted_Access = Y'Access" and so forth to match.

18740 that use (a subtype of) the class-wide type of the enclosing type.

18774 to private type.
18775 (Analyze_Subtype_Declaration): For an access subtype declaration, create

18825 * par.adb: Allow library units Calendar, Machine_Code,
18826 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
18827 when -gnatg is not specified.
18828 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
18829 there is no need to generate always a record_definition_node in case
18830 of synchronized interface types.
18831 (SIS_Entry_Active): Initialize global variable to False
18832 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

18840 is specified.
18841 (Initialize): Add the directory where gprmake is invoked in front of the
18842 path, if it is invoked from a bin directory or with directory
18843 information, so that the correct GNAT tools will be used when invoked
18844 directly.
18845 (Check_Compilation_Needed): Process correctly backslashes on Windows.
18846
18847 * vms_data.ads: Update switches/qualifiers

18851
18852 * exp_aggr.adb:
18853 If the array component is a discriminated record, the array aggregate
18854 is non-static even if the component is given by an aggregate with
18855 static components.
18856 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
18857 (Convert_Aggr_In_Allocator): If the allocator is for an access
18858 discriminant and the type is controlled. do not place on a finalization
18859 list at this point. The proper list will be determined from the
18860 enclosing object.
18861 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
18862 initialize record controller if needed, before the components, to ensure
18863 that they are properly finalized.
18864 (Build_Record_Aggr_Code): For the case of an array component that has a
18865 corresponding array aggregate in the record aggregate, perform sliding
18866 if required.

18873 run-time subprogram Set_External_Tag by call to Build_Set_External_Tag.
18874
18875 * exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
18876 accessibility on class-wide allocators if the allocator occurs at the
18877 same scope level as the allocator's type. The check is guaranteed to
18878 succeed in that case, even when the expression originates from a
18879 parameter of the containing subprogram.
18880 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
18881 under No_Dispatching_Calls restriction. During the semantic analysis
18882 we already notified such violation.

18887 to support concurrent types with interface types.
18888 (Expand_N_Allocator): Add an assertion associated with the generation
18889 of the master_id.

18900 initialize most the TSD components by means of an aggregate.
18901 Modify the declaration of the object containing the TSD
18902 because we now expand code that has a higher level of abstraction.
18903 The TSD has a discriminant containing the Inheritance Depth Level,
18904 value that is used in the membership test but also to fix the size
18905 of the table of ancestors.
18906 (Expand_Interface_Conversion): Insert function body at the closest place
18907 to the conversion expression, to prevent access-before-elaboration
18908 errors in the backend.

18914 code to return immediately if compiling under No_Dispatching_Calls
18915 restriction.
18916 (Set_All_DT_Position): Remove code associated with the old CPP pragmas.
18917 CPP_Virtual and CPP_Vtable are no longer supported.

18923 (Make_Secondary_DT): Modified to support concurrent record types.
18924 (Set_All_DT_Position): Modified to support concurrent record types.

18934 (Expand_Dispatching_Call): Replace generation of call to the run-time
18935 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
18936 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
18937 Address.
18938 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
18939 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
18940 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
18941 Build_Set_Prim_Op_Address.
18942 (Get_Remotely_Callable): Subprogram removed.
18943 (Init_Predefined_Interface_Primitives): Replace generation of call to
18944 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
18945 Prims.
18946
18947 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
18948 First (Parameter_Associations ()) with the call to First_Actual that
18949 returns an actual parameter expression for both named and positional
18950 associations.
18951
18952 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
18953 check violation of restriction No_Dispatching_Calls.

18958 First/Next_Component_Or_Discriminant
18959 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
18960 (Find_Implemented_Interface): Removed. All the calls to this subprogram
18961 specify Any_Limited_Interface, and this functionality is already
18962 provided by the function Has_Abstract_Interfaces.
18963 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
18964 support concurrent types implementing interfaces.
18965 (Find_Implemented_Interface): Removed. All the calls to this subprogram
18966 specify kind Any_Limited_Interface, and this functionality is already
18967 provided by the function Has_Abstract_Interfaces.
18968 (Remove_Side_Effects): replace Controlled_Type by
18969 CW_Or_Controlled_Type whenever the issue is related to
18970 using or not the secondary stack.
18971
18972 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
18973 P_Interface_Type_Definition to fulfill the new interface (the formal
18974 Is_Synchronized is no longer required).
18975
18976 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
18977 Update dependencies.

18986 anonymous, use finalization list of enclosing dynamic scope.
18987 (Expand_N_Package_Declaration): For a library package declaration
18988 without a corresponding body, generate RACW subprogram bodies in the
18989 spec (just as we do for the task activation call).
18990 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
18991 Is_Abstract_Type. Make sure these are called only when appropriate.
18992 Remove all code for DSP option

18998
18999 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
19000 parameter. If it is set to true, return a result capped according to
19001 the global upper bound for the index of an entry family.
19002 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
19003 (Build_Find_Body_Index): Adjust for above change.
19004 (Entry_Index_Expression): Likewise.

19009 Family_Size with 'Cap' set to true.
19010 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
19011 a protected version of an operation declared in the private part of
19012 a protected object, because they may be invoked through a callback.
19013 (Set_Privals): If the type of a private component is an anonymous access
19014 type, do not create a new itype for each protected body.
19015 If the body of a protected operation creates
19016 controlled types (including allocators for class-widetypes), the
19017 body of the corresponding protected subprogram must include a
19018 finalization list.
19019 (Build_Activation_Chain_Entity): Build the chain entity for extended
19020 return statements.
19021 (Type_Conformant_Parameters): Use common predicate Conforming_Types
19022 to determine whether operation overrides an inherited primitive.

19024 for a possible overriding candidate.
19025 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
19026 hold an actual parameter value since its initialization is separated
19027 from the the declaration. Prevents errors on null-excluding access
19028 formals.

19037 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
19038 E_Constant, depending upon Variable formal.
19039 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
19040 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
19041 parameter that requires an extra constrained parameter, declare
19042 temporary for actual as a variable, not a constant.
19043 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
19044 the unit being compiled is the one that contains the stub type.
19045 Change primitive operation name for the RACW associated with a RAS
19046 from Call to _Call so it cannot clash with any legal identifier.

19048 Is_RAS.
19049 (Append_RACW_Bodies): New subprogram.
19050 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
19051 Add_Receiving_Stubs_To_Declarations functions.
19052 When expanding a package body, this list correspond to the
19053 statements in the HSS at the end of the pacakge.
19054 When expanding a package spec, this list correspond to the
19055 spec declarations.
19056 (Add_Receiving_Stubs_To_Declarations): Append the function
19057 registering the receiving stubs at the end of the 'Stmts' list.
19058 (RCI_Package_Locator): Pass the new Version generic formal when
19059 instantiating a RCI_Locator package.
19060 (Build_From_Any_Function): To compute the High bound for an
19061 unconstrained array actual, we add the Low bound with the length.
19062 Thus we must convert the low bound and the length to an appropriate
19063 type before doing the sum.
19064 (Build_Subprogram_Receiving_Stubs, PolyORB):
19065 * Retrieve the extra formals parameters at the
19066 end of the parameter stream.
19067 * Use Move_Any_Value to write back out parameters
19068 after executing the request as it is more efficient
19069 than Copy_Any_Value.
19070 * Build the any containing Extra Formals with the
19071 appropriate typecode.
19072 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an

19081 Extra Constrained Parameters.
19082 (Build_General_Calling_Stubs): Set the parameter type to boolean for

19086 function with the first not implicit parent type.
19087 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
19088 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
19089 typecode from the Etype. Therefore we retrieve the correct typecode
19090 with a call to Get_Any_Type.
19091 (Copy_Specification): Do controlling formal type substitution based on
19092 Is_Controlling_Formal flag, instead of caller-provided object type.
19093 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
19094 a RACW primitive operation, we might get a subprogram declaration for an
19095 ancestor of the RACW designated type (not for the designated type
19096 itself), in the case where this operation is inherited. In this case we
19097 have no easy means of determining the original tagged type for which
19098 the primitive was declared, so instead we now rely on
19099 Copy_Specification to use the Is_Controlling_Formal flag to determine
19100 which formals require type substitution.

19109 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
19110 run-time subprogram CW_Membership by call to Build_CW_Membership.
19111 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
19112 by a function call, a temporary must be created before expanding the
19113 Constructor_Call itself, to prevent out-of-order elaboration in the
19114 back-end when stack checking is enabled..

19234
19235 * i-cstrea.ads: (fopen): Add encoding parameter.
19236 (freopen): Idem.
19237 Change reference from a-sysdep.c to sysdep.c in comment.
19238 Update copyright notice.
19239 This set of patch add support for the encoding form parameter.
19240
19241 * mingw32.h (S2WSU): New macro to convert from a string to a
19242 wide-string using the UTF-8 encoding. The S2WS macro supports now only
19243 standard 8bits encoding.
19244 (WS2SU): As above but converting from wide-sring to string.
19245 This is needed as it is necessary to have access to both versions in the
19246 runtime for the form parameter encoding support.
19247 This set of patch add support for the encoding form parameter.
19248 (S2WS): Improve implementation to handle cases where the filename is not
19249 UTF-8 encoded. In this case we default to using the current code page
19250 for the conversion.
19251
19252 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
19253 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match
19254 the constants defined in adaint.h.
19255 (fopen): Add encoding parameter.
19256 (freopen): Idem.
19257
19258 * s-ficobl.ads (AFCB): Add Encoding field to record the filename
19259 encoding. This is needed for the Reset routine (freopen low level-call).
19260
19261 * s-fileio.adb (Open): Decode encoding form parameter and set the
19262 corresponding encoding value into AFCB structure.
19263 (Reset): Pass the encoding value to freopen.
19264 (Close): Move the call to Lock_Task to the beginning of the procedure.

19297 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
19298 __gnat_adjust_context_for_raise.
19299 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
19300 implementation of floating point operations as native x86 targets.
19301 So the FPU should be initialized in the same way using finit. Fix
19302 floating point operations accuracy issues.
19303 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
19304 member in struct sigaction, so as to avoid warning for incompatible
19305 pointer types.

19324 types that the type implements. List each of these interfaces when
19325 building the entry for the type.
19326 (Generate_Definition): Initialize component Def and Typ of new entry
19327 in table Xrefs, to avoid to have these components unitialized.
19328 (Output_References): Split Is_Abstract flag into
19329 Is_Abstract_Subprogram and Is_Abstract_Type.
19330 (Generate_Reference): Add barrier to do not generate the warning
19331 associated with Ada 2005 entities with entities generated by the
19332 expander.

193712007-04-06 Robert Dewar <dewar@adacore.com>
19372
19373 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
19374 it no longer destroys the contents of Name_Buffer or Name_Len and
19375 non-standard and invalid names are handled better.
19376 (Get_Decoded_Name_String): Improve performance by using
19377 Name_Has_No_Encodings flag in the name table.

19390 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
19391 illegal in Ada 95, in cases where it is legal. Change the warnings to
19392 errors in other cases. Don't give the error unless the "not null"
19393 parses properly. Correct the source position at which the error occurs.
19394 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
19395 P_Null_Exclusion, to suppress "not null" warnings.
19396 (P_Identifier_Declarations): Code cleanup. Removed unrequired label and
19397 associated goto statements.
19398
19399 * par-endh.adb (Pop_End_Context): Allow more flexibility in placement
19400 of END RECORD
19401

19403
19404 * par-ch6.adb (P_Mode): Check specifically for case of IN ACCESS
19405 (P_Formal_Part): Pass Allow_Anonymous_In_95 => True to

19437 Shared_Library_Minimum_Options,
19438 Shared_Library_Prefix, Shared_Library_Suffix, Symbolic_Link_Supported.

19448
19449 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
19450 switches, without repetition of "eD". Make sure that last character of
19451 -gnatep= switch is not taken as -gnat switch character.
19452 Complete rewrite of circuit for handling saving compilation options
19453 Occasioned by need to support dot switchs for -gnatw, but cleans up
19454 things in general.
19455 -gnatX does not affect Ada_Version
19456 Include -gnatyA in -gnatg style switches

19471 the default project path, initially done during elaboration of the
19472 package.
19473 If the prefix returned by Sdefault is null, get the prefix from a call
19474 to Executable_Prefix_Path.
19475 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
19476 null.
19477
19478 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
19479 canonical directory name to open the directory from which files are
19480 retrieved.

19486 library source copy dir and exec dir.
19487
19488 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older

19513
19514 * opt.ads: (Warn_On_Non_Local_Exception): New flag
19515 (Warn_On_Reverse_Bit_Order): New flag
19516 (Extensions_Allowed): Update the documentation.
19517 (Warn_On_Questionable_Missing_Parens): Now on by default

19524
19525 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
19526 full word is no longer compared twice.
19527
195282007-04-06 Ed Schonberg <schonberg@adacore.com>
19529
19530 * sem_ch10.adb (Install_Limited_Context_Clauses.
19531 Expand_Limited_With_Clause): Use a new copy of selector name in the
19532 call to Make_With_Clause. This fixes the tree structure for ASIS
19533 purposes. Nothing is changed in the compiler behaviour.
19534 (Process_Body_Clauses): Handle properly use clauses whose prefix is
19535 a package renaming.
19536 (Install_Limited_With_Clauses): Do not install non-limited view when it
19537 is still incomplete.
19538
195392007-04-06 Ed Schonberg <schonberg@adacore.com>
19540 Gary Dismukes <dismukes@adacore.com>
19541
19542 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
19543 when capturing size information, instead of base type, which for a
19544 formal array type will be the unconstrained type.
19545 (Analyze_Formal_Object_Declaration): Add check for illegal default
19546 expressions for a formal in object of a limited type.
19547 (Instantiate_Object): Ditto.
19548 (Check_Formal_Package_Instance): Skip entities that are formal objects,
19549 because they were defaulted in the formal package and no check applies
19550 to them.
19551 (Check_Formal_Package_Instance): Extend conformance check to other
19552 discrete types beyond Integer.
19553 (Process_Default): Copy directly the unmatched formal. A generic copy
19554 has already been performed in Analyze_Formal_Package.
19555 (Analyze_Associations): If a formal subprogram has no match, check for
19556 partial parametrization before looking for a default, to prevent
19557 spurious errors.
19558 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
19559 not set the instantiation environment before analyzing the actuals.
19560 Fixes regression on 8515-003 with implementation of AI-133.
19561 Set_Instance_Env checks whether the generic unit is a predefined
19562 unit, in which case the instance must be analyzed with the latest Ada
19563 mode. This setting must take place after analysis of the actuals,
19564 because the actuals must be analyzed and frozen in the Ada mode extant
19565 outside of the current instantiation.
19566 (Save_Env, Restore_Env): Preserve and restore the configuration
19567 parameters so that predefined units can be compiled in the proper Ada
19568 mode.
19569 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
19570 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
19571 and Is_Abstract_Type.
19572 (Analyze_Formal_Package): For better error recovery, Add exception
19573 handler to catch Instantion_Error, which can be raised in
19574 Analyze_Associations
19575
195762007-04-06 Ed Schonberg <schonberg@adacore.com>
19577 Bob Duff <duff@adacore.com>
19578 Gary Dismukes <dismukes@adacore.com>
19579
19580 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
19581 prefix type is a discriminated subtype of the type of the formal.
19582 (Analyze_Allocator): Collect all coextensions regardless of the context.
19583 Whether they can be allocated statically is determined in exp_ch4.
19584 (Analyze_Selected_Component): If the prefix is a limited view and the
19585 non-limited view is available, use the non-limited one.
19586 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
19587 therefore illegal), suggest a qualified expression rather than a type
19588 conversion, because a type conversion would be illegal in this context.
19589 (Anayze_Allocator): Trace recursively all nested allocators so that all
19590 coextensions are on the corresponding list for the root. Do no mark
19591 coextensions if the root allocator is within a declaration for a stack-
19592 allocated object, because the access discriminants will be allocated on
19593 the stack as well.
19594 (Analyze_Call): Remove restriction on calls to limited functions for the
19595 cases of generic actuals for formal objects, defaults for formal objects
19596 and defaults for record components.
19597 (Analyze_Allocator): Before analysis, chain coextensions on the proper
19598 element list. Their expansion is delayed until the enclosing allocator
19599 is processed and its finalization list constructed.
19600 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
19601 for an operation with the given name among the primitive operations of
19602 the corresponding record type.
19603 (Analyze_Selected_Component): If the prefix is a task type that
19604 implements an interface, and there is no entry with the given name,
19605 check whether there is another primitive operation (e.g. a function)
19606 with that name.
19607 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
19608 properly the indexing of a function call written in prefix form, where
19609 the function returns an array type, and all parameters of the function
19610 except the first have defaults.
19611 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
19612 the original operands, rather than relocating them, for efficiency and
19613 to work properly when an operand is overloaded.
19614 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
19615 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
19616 (Analyze_Selected_Component): If the prefix is a private extension, only
19617 scan the visible components, not those of the full view.
19618 (Try_Primitive_Operation): If the operation is a procedure, collect all
19619 possible interpretations, as for a function, because in the presence of
19620 classwide parameters several primitive operations of the type can match
19621 the given arguments.

19624 Robert Dewar <dewar@adacore.com>
19625
19626 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
19627 tag-indeterminate call to an abstract function, when the left-hand side
19628 is not classwide.
19629 (Analyze_Loop_Statement): Improve detection of infinite loops
19630

19632 Thomas Quinot <quinot@adacore.com>
19633
19634 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
19635 out of Analyze_Package_Declaration, because processing must be applied
19636 to package bodies as well, for deferred constants completed by pragmas.
19637 (Analyze_Package_Declaration): When the package declaration being
19638 analyzed does not require an explicit body, call Check_Completion.
19639 (May_Need_Implicit_Body): An implicit body is required when a package
19640 spec contains the declaration of a remote access-to-classwide type.
19641 (Analyze_Package_Body): If the package contains RACWs, append the

20029 that expects any real type. Also set the type of the node to
20030 Universal_Real in this case, because downstream processing requires it
20031 (mainly static expression evaluation).
20032 Reword some continuation messages
20033 Add some \\ sequences to continuation messages
20034 (Resolve_Call): Refine infinite recursion case. The test has been
20035 sharpened to eliminate some false positives.

20037 warning, not an error.
20038 (Resolve): If the call is ambiguous, indicate whether an interpretation
20039 is an inherited operation.

20048 during analysis, and use May_Be_Lvalue to distinguish read/write.
20049 (Valid_Array_Conversion): New procedure, abstracted from
20050 Valid_Conversion, to incorporate accessibility checks for arrays of
20051 anonymous access types.
20052 (Valid_Conversion): For a conversion to a numeric type occurring in an
20053 instance or inlined body, no need to check that the operand type is
20054 numeric, since this has been checked during analysis of the template.
20055 Remove legacy test for scope name Unchecked_Conversion.

20335 type_decl is properly set before calling the debug information writers.
20336 (write_record_type_debug_info): The heuristics which compute the
20337 alignment of a field in a variant record might not be accurate. Add a
20338 safety test to make sure no alignment is set to a smaller value than
20339 the alignment of the field type.
20340 (make_dummy_type): Use the Non_Limited_View as the underlying type if
20341 the type comes from a limited_with clause. Do not loop on the full view.

20808 subcomponent's enclosing variable is aliased with a constrained subtype.
20809 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
20810 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
20811 an aliased prefix must be known to be constrained in order to use True
20812 for the attribute value, and now it's possible for some aliased views
20813 to be unconstrained.
20814
208152006-10-31 Robert Dewar <dewar@adacore.com>
20816
20817 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
20818 (Expand_Entity_Reference): Correct error of not handling subprogram
20819 formals in current_value processing.

20825
6f7f72f9 20826 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
70198b9f
AC		 20827 register in the final list objects containing class-wide interfaces;
20828 otherwise we incorrectly register the tag of the interface in the final
20829 list.
6f7f72f9
EB		 20830 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
20831 generate the wrapper if the parent primitive is abstract. This is
20832 required to report the correct error message.
20833 (Expand_N_Subtype_Indication): Do validity checks on range
70198b9f
AC		 20834 (Clean_Task_Names): If an initialization procedure includes a call to
20835 initialize a task (sub)component, indicate that the procedure will use
20836 the secondary stack.
20837 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
20838 compatibility for interfacing with CPP by default.
20839 (Expand_N_Object_Declaration): Only build an Adjust call when the
20840 object's type is a nonlimited controlled type.
20841 * exp_ch3.adb: Add with and use of Exp_Ch6.
20842 (Expand_N_Object_Declaration): Check for object initialization that is a
20843 call to build-in-place function and apply Make_Build_In_Place_Call_In_
20844 Object_Declaration to the call.
20845 (Freeze_Type): When the designated type of an RACW was not frozen at the
20846 point where the RACW was declared, validate the primitive operations
20847 with respect to E.2.2(14) when it finally is frozen.
20848 (Build_Initialization_Call,Expand_Record_Controller): Rename
20849 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
20850 return-by-reference has no meaning in Ada 2005.
20851 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
20852 to register tag of the immediate ancestor interfaces in the
20853 run-time structure.
20854 (Init_Secondary_Tags): Moved to the specification to allow the
20855 initialization of extension aggregates with abstract interfaces.
20856 (Build_Master_Renaming): Make public, for use by function declarations
20857 whose return type is an anonymous access type.
20858 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
20859 Insert_List_Before_And_Analyze after the generation of the specs
20860 associated with null procedures.
20861 (Expand_Tagged_Root): Update documentation in its specification.
20862 (Init_Secondary_Tags): Update documentation.
20863 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
20864 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
20865 then generate code to inherit the contents of the dispatch table
20866 directly from the ancestor.
20867 (Expand_Record_Controller): Insert controller component after tags of
20868 implemented interfaces.
20869 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
20870 create null procedure overridings when null procedures are inherited
20871 from interfaces.
20872 (Make_Null_Procedure_Specs): New procedure to generate null procedure
20873 declarations for overriding null primitives inherited from interfaces.
20874 (Is_Null_Interface_Procedure): New function in
20875 Make_Null_Procedure_Specs.
20876 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
20877 immediate ancestor of a tagged type is an abstract interface type we
20878 must generate the specification of the predefined primitives associated
20879 with controlled types (because the dispatch table of the ancestor is
20880 null and hence these entries cannot be inherited). This is required to
20881 elaborate well the dispatch table.

6f7f72f9 20891 (Expand_N_In): Do validity checks on range
70198b9f
AC		 20892 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
20893 (Expand_N_Allocator): For "new T", if the object is constrained by
20894 discriminant defaults, allocate the right amount of memory, rather than
20895 the maximum for type T.
20896 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
20897 when the allocator is initialized by a build-in-place call, since the
20898 allocator is already rewritten as a reference to the function result,
20899 and this prevents an unwanted duplication of the function call.
20900 Add with and use of Exp_Ch6.
20901 (Expand_Allocator_Expresssion): Check for an allocator whose expression
20902 is a call to build-in-place function and apply
20903 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
20904 untagged designated types).
20905 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
20906 optimization if source or target is biased.
20907 (Expand_N_Allocator): Add comments for case of an allocator within a
20908 function that returns an anonymous access type designating tasks.
20909 (Expand_N_Allocator): apply discriminant checks for access

6f7f72f9 20919 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
70198b9f
AC		 20920 (Expand_N_Assignment_Statement): Call
20921 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
20922 build-in-place function call. Currently, this can happen only for
20923 assignments that come from aggregates.
20924 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
20925 in order to alleviate the upward compatibility introduced by AI-318.
20926 (Expand_N_Extended_Return_Statement): Add support for handling the
20927 return object as a build-in-place result.
20928 (Expand_Non_Function_Return): Implement simple return statements nested
20929 within an extended return.
20930 (Enable_New_Return_Processing): Turn on the new processing of return
20931 statements.
20932 (Expand_Non_Function_Return): For a return within an extended return,
20933 don't raise Program_Error, because Sem_Ch6 now gives a warning.
20934 (Expand_N_Extended_Return_Statement): Implement AI-318
20935 (Expand_Simple_Function_Return): Ditto.
20936 (Expand_N_If_Statement): Handle new -gnatwt warning
20937 (Expand_N_Case_Statement): Handle new -gnatwt warning
20938 (Expand_N_Assignment): Handle assignment to the Priority attribute of
20939 a protected object.
20940 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
20941 validity checking of assignments to elementary record components.
20942 (Expand_N_Return_Statement): return Class Wide types on the secondary
20943 stack independantly of their controlled status since with HIE runtimes,
20944 class wide types are not potentially controlled anymore.
20945
20946 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
20947 node kind.
20948
20949 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
20950 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
20951 it expects a block, procedure, or task. The return statement will get
20952 turned into a block, and Expand_Cleanup_Actions will happen then.

20958
20959 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
20960 capability.
20961 (Expand_Inlined_Call): Tagged types are by-reference types, and
20962 therefore should be replaced by a renaming declaration in the expanded
20963 body, as is done for limited types.
20964 (Expand_Call): If this is a call to a function with dispatching access
20965 result, propagate tag from context.
20966 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
20967 CPP by default.
20968 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
20969 build-in-place when the right-hand side of an assignment is a
20970 build-in-place function call.
20971 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
20972 of the explicit dereference of the allocator to the result subtype of
20973 the build-in-place function. This is needed to satisfy type checking
20974 in cases where the caller's return object is created by an allocator for
20975 a class-wide access type and the type named in the allocator is a
20976 specific type.
20977 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
20978 conversion of the reference to the declared object to the result subtype
20979 of the build-in-place function. This is needed to satisfy type checking
20980 in cases where the declared object has a class-wide type. Also, in the
20981 class-wide case, change the type of the object entity to the specific
20982 result subtype of the function, to avoid passing a class-wide object
20983 without explicit initialization to the back end.
20984 (Register_Interface_DT_Entry): Moved outside the body of
20985 Freeze_Subprogram because this routine is now public; it is called from
20986 Check_Dispatching_Overriding to handle late overriding of abstract
20987 interface primitives.
20988 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
20989 adding an implicit access actual on a call to a build-in-place function.
20990 (Expand_Actuals): Test for an actual parameter that is a call to a
20991 build-in-place function and apply
20992 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
20993 (Is_Build_In_Place_Function): New function to determine whether an
20994 entity is a function whose calls should be handled as build-in-place.
20995 (Is_Build_In_Place_Function_Call): New function to determine whether an
20996 expression is a function call that should handled as build-in-place.
20997 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
20998 calls to build-in-place functions as the initialization of an allocator.
20999 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
21000 handling calls to build-in-place functions in contexts that do not
21001 involve init of a separate object (for example, actuals of subprogram
21002 calls).
21003 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
21004 handling calls to build-in-place functions as the initialization of an
21005 object declaration.
21006 (Detect_Infinite_Recursion): Add explicit parameter Process to
21007 instantiation of Traverse_Body to avoid unreferenced warning.
21008 (Check_Overriding_Inherited_Interfaces): Removed.
21009 (Register_Interface_DT_Entry): Code cleanup.
21010 (Register_Predefined_DT_Entry): Code cleanup.
21011 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
21012 inlined statements if within a transient scope.
21013 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
21014 formal parameters with occurrences of actuals in inlined body, establish
21015 visibility on the proper view of the actual's subtype for the body's
21016 context.
21017 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
21018 compatibility mode and we have an imported CPP subprogram because
21019 for now we assume that imported CPP primitives correspond with
21020 objects whose constructor is in the CPP side (and therefore we
21021 don't need to generate code to register them in the dispatch table).
21022 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
21023 aligned selected component.
21024 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
21025 the actual of an in-mode parameter is a type conversion.
21026 (Expand_Actuals): If the call does not come from source and the actual
21027 is potentially misaligned, let gigi handle it rather than rejecting the
21028 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
21029 Class Wide types as returning by reference independantly of their
21030 controlled status since with HIE runtimes class wide types are not
21031 potentially controlled anymore.

21038 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
21039 instantiation to deal with warnings.
21040 (Initialize_Protection): If expression for priority is non-static, use
21041 System_Priority as its expected type, in case the expression has not
21042 been analyzed yet.

21059 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
21060 should be done only once they are assigned.
21061 (Build_From_Any_Function, case of tagged types): Add missing call to
21062 Allocate_Buffer.
21063 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
21064 type for an RACW type.
21065 (Add_RACW_Features): When processing an RACW declaration for which the
21066 designated type is already frozen, enforce E.2.2(14) rules immediately.
21067 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any

21087 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
21088 it on to the Value_Wide_Wide_Character call.
21089 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
21090 properly handles a string of the form quote-encoded_wide_char-quote.

21105 equivalent to pragma Import.
21106
21107 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
21108 so that it can be applied to all entities, including record components
21109 and enumeration literals.
21110 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
21111 priority ranges are correct, verify compatibility against task
21112 dispatching and locking policies, and if everything is correct an entry
21113 is added to the table containing priority specific dispatching entries
21114 for this compilation unit.
21115 (Delay_Config_Pragma_Analyze): Delay processing
21116 Priority_Specific_Dispatching pragmas because when processing the
21117 pragma we need to access run-time data, such as the range of
21118 System.Any_Priority.
21119 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
21120 Allow pragma Unreferenced as a context item
21121 Add pragma Preelaborable_Initialization

21140 in Ada 2005.
21141 (Find_Node_To_Be_Wrapped): Use new method of determining the result
21142 type of the function containing a return statement, because the

21157 attempts to save information for global variables which cannot be
21158 safely tracked.

21162 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
21163 (Get_Current_Value_Condition): Handle simple boolean operands

21165 (Get_Current_Value_Condition): If the variable reference is within an
21166 if-statement, does not appear in the list of then_statments, and does
21167 not come from source, treat it as being at unknown location.
21168 (Get_Current_Value_Condition): Enhance to allow while statements to be
21169 processed as well as if statements.
21170 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
21171 come from source.
21172 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
21173 of loop. This is safe now that we fixed Kill_Current_Values.

21201 main unit, if it is the generic body corresponding to an subprogram
21202 instantiation.
21203
21204 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
21205
6f7f72f9 21206 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
70198b9f
AC		 21207 -gnatwq/Q.
21208 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
21209 exception handler.
21210 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
21211 use clauses, to avoid messages on packages used to qualify, and also
21212 to avoid messages from obsolescent units.
21213 (Warn_On_Useless_Assignments): Don't generate messages for imported
21214 and exported variables.
21215 (Warn_On_Useless_Assignments): New procedure
21216 (Output_Obsolescent_Entity_Warnings): New procedure
21217 (Check_Code_Statement): New procedure
21218
6f7f72f9 21219 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
70198b9f
AC		 21220 Change name Is_Ada_2005 to Is_Ada_2005_Only
21221 (Last_Assignment): New field for useless assignment warning
21222
212232006-10-31 Olivier Hainque <hainque@adacore.com>
21224
21225 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
21226 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
21227
212282006-10-31 Bob Duff <duff@adacore.com>
21229 Robert Dewar <dewar@adacore.com>
21230 Ed Schonberg <schonberg@adacore.com>
21231
21232 * g-awk.adb (Default_Session, Current_Session): Compile this file in
21233 Ada 95 mode, because it violates the new rules for AI-318.
21234
21235 * g-awk.ads: Use overloaded subprograms in every case where we used to
21236 have a default of Current_Session. This makes the code closer to be
21237 correct for both Ada 95 and 2005.
21238
21239 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
21240 code, relying on the fact that the compiler generates a warning
21241 instead of an error in -gnatg mode.
21242
21243 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
21244 E_Return_Statement entity kind.
21245 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
21246
21247 * par.adb (P_Interface_Type_Definition): Addition of one formal to
21248 report an error if the reserved word abstract has been previously found.
21249 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
6f7f72f9
EB		 21250
21251 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
70198b9f
AC		 21252 parenthesized range attribute usage
21253 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
21254
21255 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
21256 in the syntax for extended_return_statement. This is not in the latest
21257 RM, but the ARG is expected to issue an AI allowing this.
21258 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
21259 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
21260 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
21261 P_Return_Statement): Parse the new syntax for extended_return_statement.
21262
21263 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
21264 Output_End_Missing): Add error-recovery code for the new
21265 extended_return_statement syntax; that is, the new E_Return entry on
21266 the scope stack.
21267
21268 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
21269 limited to nonlimited, because otherwise we violate the new Ada 2005
21270 rules about returning limited types in function Create_AST_Handler in
21271 s-asthan.adb.
21272
21273 * sem.adb (Analyze): Add cases for new node kinds
21274 N_Extended_Return_Statement and N_Return_Object_Declaration.
21275
21276 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
21277 type is in the same category as type of context before applying check,
21278 to prevent anomalies in instantiations.
21279 (Resolve_Aggregate): Remove test for limited components in aggregates.
21280 It's unnecessary in Ada 95, because if it has limited components, then
21281 it must be limited. It's wrong in Ada 2005, because limited aggregates
21282 are now allowed.
21283 (Resolve_Record_Aggregate): Move check for limited types later, because
21284 OK_For_Limited_Init requires its argument to have been resolved.
21285 (Get_Value): When copying the component default expression for a
21286 defaulted association in an aggregate, use the sloc of the aggregate
21287 and not that of the original expression, to prevent spurious
21288 elaboration errors, when the expression includes function calls.
21289 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
21290 were missing. We also didn't handle qualified expressions. Now also
21291 allow function calls. Use new common routine OK_For_Limited_Init.
21292 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
21293 with space can upper case letter).
21294
6f7f72f9 21295 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
70198b9f 21296 Has_Static_Discriminants flag
6f7f72f9
EB		 21297 (Record_Type_Declaration): Diagnose an attempt to declare an interface
21298 type with discriminants.
21299 (Process_Range_Expr_In_Decl): Do validity checks on range
70198b9f
AC		 21300 (Build_Discriminant_Constraints): Use updated form of
21301 Denotes_Discriminant.
21302 (Process_Subtype): If the subtype is a private subtype whose full view
21303 is a concurrent subtype, introduce an itype reference to prevent scope
21304 anomalies in gigi.
21305 (Build_Derived_Record_Type, Collect_Interface_Primitives,
21306 Record_Type_Declaration): The functionality of the subprograms
21307 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
21308 is now performed by a single routine.
21309 (Build_Derived_Record_Type): If the type definition includes an explicit
21310 indication of limitedness, then the type must be marked as limited here
21311 to ensure that any access discriminants will not be treated as having
21312 a local anonymous access type.
21313 (Check_Abstract_Overriding): Issue a detailed error message when an
21314 abstract subprogram was not overridden due to incorrect mode of its
21315 first parameter.
21316 (Analyze_Private_Extension_Declaration): Add support for the analysis of
21317 synchronized private extension declarations. Verify that the ancestor is
21318 a limited or synchronized interface or in the generic case, the ancestor
21319 is a tagged limited type or synchronized interface and all progenitors
21320 are either limited or synchronized interfaces.
21321 Derived_Type_Declaration): Check for presence of private extension when
21322 dealing with synchronized formal derived types.
21323 Process_Full_View): Enchance the check done on the usage of "limited" by
21324 testing whether the private view is synchronized.
21325 Verify that a synchronized private view is completed by a protected or
21326 task type.
21327 (OK_For_Limited_Init_In_05): New function.
21328 (Analyze_Object_Declaration): Move check for limited types later,
21329 because OK_For_Limited_Init requires its argument to have been resolved.
21330 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
21331 in order to alleviate the upward compatibility introduced by AI-318.
21332 (Constrain_Corresponding_Record): If the constraint is for a component
21333 subtype, mark the itype as frozen, to avoid out-of-scope references to
21334 discriminants in the back-end.
21335 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
21336 this subprogram against wrong sources.
21337 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
21338 discriminant of limited type completed with a protected type, when the
21339 discriminant is used to constrain a private component of the type, and
21340 expansion is disabled.
21341 (Find_Type_Of_Object): Do not treat a return subtype that is an
21342 anonymous subtype as a local_anonymous_type, because its accessibility
21343 level is the return type of the enclosing function.
21344 (Check_Initialization): In -gnatg mode, turn the error "cannot
21345 initialize entities of limited type" into a warning.
21346 (OK_For_Limited_Init): Return true for generated nodes, since it
21347 sometimes violates the legality rules.
21348 (Make_Incomplete_Declaration): If the type for which an incomplete
21349 declaration is created happens to be the currently visible entity,
21350 preserve the homonym chain when removing it from visibility.
21351 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
21352 inherited subprograms.
21353 (Access_Definition): If this is an access to function that is the return
21354 type of an access_to_function definition, context is a type declaration
21355 and the scope of the anonymous type is the current one.
21356 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
21357 incomplete subtype to the set of private dependents of the original
21358 incomplete type.
21359 (Constrain_Discriminated_Type): Emit an error message whenever an
21360 incomplete subtype is being constrained.
21361 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
21362 corresponding subtype of the full view of the original incomplete type.
21363 (Check_Incomplete): Properly detect invalid usage of incomplete types
21364 and subtypes.
21365

21377 Robert Dewar <dewar@adacore.com>
21378
21379 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
21380 handling executable extension manually and duplicating code.
21381
21382 * make.adb: Implement new -S switch
21383 (Gnatmake): Use new function Osint.Executable_Name instead
21384 of handling executable extension manually.
21385
21386 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
21387 is specified, the executable name ends with this suffix.
21388 Take advantage of Osint.Executable_Name instead of duplicating code.
21389
21390 * switch-m.adb: Recognize new gnatmake -S switch
21391
21392 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
21393 variable.
21394 (Get_Target_Parameters): Set Executable_Extension_On_Target if
21395 available.
21396

21398
213992006-10-31 Vincent Celier <celier@adacore.com>
21400
21401 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
21402 call it with -static-libgcc, as there are some platforms, such as
21403 Darwin, where one of these two switches is compulsory to link.
21404
214052006-10-31 Vincent Celier <celier@adacore.com>
6f7f72f9 21406
70198b9f
AC		 21407 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
21408 instead of ADA_PROJECT_PATH, for the project path.
21409 (Gnatls): When displaying the project path directories, use host dir
21410 specs.
21411
21412 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
21413 names in the project path, as absolute paths may correspond to
21414 multi-valued VMS logical names.
21415
214162006-10-31 Vincent Celier <celier@adacore.com>
21417
21418 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
21419 absolute path name.
21420 (Locate_Regular_File): Ditto
21421 (Change_Dir): Remove, no longer used
21422 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
21423 on Windows. Get it calling Get_Current_Dir.

21425 (Normalize_Pathname)[VMS]: Do not resolve directory names.
21426 (Pid_To_Integer): New function to convert a Process_Id to Integer

214282006-10-31 Thomas Quinot <quinot@adacore.com>
21429
21430 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
21431 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
21432 to No_Socket.
21433 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
21434 W_Sig_Socket.
21435

6f7f72f9
EB		 21447 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
21448 variant records
21449 (Layout_Variant_Record): Retrieve the discriminants from the entity
70198b9f
AC		 21450 rather than from the type definition, because in the case of a full
21451 type for a private type we need to take the discriminants from the
21452 partial view.
6f7f72f9
EB		 21453 (Layout_Component_List): When applying the Max operator to variants with
21454 a nonstatic size, check whether either operand is static and scale that
21455 operand from bits to storage units before applying Max.
70198b9f
AC		 21456 (Layout_Type): In VMS, if a C-convention access type has no explicit
21457 size clause (and does not inherit one in the case of a derived type),
21458 then the size is reset to 32 from 64.
21459
214602006-10-31 Vincent Celier <celier@adacore.com>
21461
21462 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
21463 its file has already been loaded, according to the unit being loaded,
21464 not to the current value of Multiple_Unit_Index.
21465
214662006-10-31 Thomas Quinot <quinot@adacore.com>

21491
214922006-10-31 Vincent Celier <celier@adacore.com>
21493
21494 * mlib-utl.adb (Initialized): Remove, no longer used
21495 (Initialize): Remove, no longer used
21496 (Ar): If Ar_Exec is null, get the location of the archive builder and,
21497 if there is one, the archive indexer. Fail if the archive builder cannot
21498 be found.
21499 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
21500 be found.
21501
215022006-10-31 Ed Schonberg <schonberg@adacore.com>
21503
21504 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
21505 Process_Body_Clauses): If the context of a body includes a use clause
21506 for P.Q then a with_clause for P in the same body is not redundant,
21507 even if the spec also has a with_clause on P.
21508 Add missing continuation mark to error msg
21509 (Build_Limited_Views): A limited view of a type is tagged if its
21510 declaration includes a record extension.
21511 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
21512 node, even if the subunit has errors. This avoids malfunction by
21513 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
21514 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
21515 generation of obsolescent messages for with statements (cannot do
21516 this too early, or we cannot implement avoiding the messages in the
21517 case of obsolescent units withing obsolescent units).
21518 (Install_Siblings): If the with_clause is on a remote descendant of
21519 an ancestor of the current compilation unit, find whether there is
21520 a sibling child unit that is immediately visible.
21521 (Remove_Private_With_Clauses): New procedure, invoked after completing
21522 the analysis of the private part of a nested package, to remove from
21523 visibility the private with_clauses of the enclosing package
21524 declaration.
21525 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
21526 now centralized in Generate_Reference.
21527 (Install_Limited_Context_Clauses): Remove superfluous error
21528 message associated with unlimited view visible through use
21529 and renamings. In addition, at the point in which the error
21530 is reported, we add the backslash to the text of the error
21531 to ensure that it is reported as a single error message.
21532 Use new // insertion for some continuation messages
21533 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
21534 to create implicit with_clause for parent unit mentioned in original
21535 limited_with_clause.
21536 (Install_Limited_With_Unit): Set entity of parent identifiers if the
21537 unit is a child unit. For ASIS queries.
21538 (Analyze_Subunit): If the subunit appears within a child unit, make all
21539 ancestor child units directly visible again.

21551 Add the new actual Abstract_Present to every call to
21552 P_Interface_Type_Definition.
21553 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
21554 a formal object declaration with an access definition or a subtype mark
21555 with a null exclusion.
21556 (P_Generic_Association): Handle association with box, and others_choice
21557 with box, to support Ada 2005 partially parametrized formal packages.

21566 private extensions.
21567 (P_Type_Declaration): Add the new actual Abstract_Present to every call
21568 to P_Interface_Type_Definition.
21569 (P_Interface_Type_Definition): Addition of one formal to report an error
21570 if the reserved word abstract has been previously found.

21572 object renaming declaration with an access definition or subtype mark
21573 with a possible null exclusion.

21599 (Record_Ada_Source): Always add the source file name in the list of
21600 of sources, even if it is not the first time, as it is for another
21601 source index.
21602 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single

21621 desirable because we do not want to modify code in the case where only
21622 a warning is set.
21623 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
21624 causes overriding of real restrictions.

21655 properly an attempt to apply Unchecked_Access to a protected operation.
21656 (OK_Self_Reference): New subprogram to check the legality of an access
21657 attribute whose prefix is the type of an enclosing aggregate.
21658 Generalizes previous mechanism to handle attribute references nested
21659 arbitrarily deep within the aggregate.
21660 (Analyze_Access_Attribute): An access attribute whose prefix is a type
21661 can appear in an aggregate if this is a default-initialized aggregate
21662 for a self-referential type.
21663 (Resolve_Attribute, case Access): Ditto.
21664 Add support for new implementation defined attribute Stub_Type.
21665 (Eval_Attribute, case Attribute_Stub_Type): New case.
21666 (Analyze_Attribute, case Attribute_Stub_Type): New case.
21667 (Stream_Attribute_Available): Implement using new subprogram from
21668 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
21669 Has_Specified_Stream_Attribute flag.
21670 Disallow Storage_Size and Storage_Pool for access to subprogram
21671 (Resolve_Attribute, case 'Access et al): Take into account anonymous
21672 access types of return subtypes in extended return statements. Remove
21673 accessibility checks on anonymous access types when Unchecked_Access is
21674 used.

21676 a class-wide interface to a tagged type.
21677 Add support for the attribute Priority.
21678 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
21679 whether the designated type is discriminated with a constrained partial
21680 view and require static matching in that case.
21681 Add local variable Des_Btyp. The Designated_Type
21682 of an access to incomplete subtype is either its non-limited view if
21683 coming from a limited with or its etype if regular incomplete subtype.
21684
21685 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
21686 Fix predicate to identify and allow cases of (expander-generated)
21687 references to tag of designated object of a RACW.
21688 (Validate_Static_Object_Name): In Ada 2005, a formal object is
21689 non-static, and therefore cannot appear as a primary in a preelaborable
21690 package.
21691 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
21692 Has_Read_Write_Attributes.
21693 (Has_Read_Write_Attributes): Reimplement in termes of
21694 Has_Stream_Attribute_Definition.
21695 (Missing_Read_Write_Attributes): When checking component types in a
21696 record, unconditionally call Missing_Read_Write_Attributes recursively
21697 (remove guard checking for Is_Record_Type / Is_Access_Type).

70198b9f
AC		 21711 that has been constant-folded, preserve information of original tree,
21712 for ASIS uses.
21713 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
21714 generated private extension declaration if the formal derived type is
21715 synchronized. Carry synchronized present over to the generated private
21716 extension.
21717 (Validate_Derived_Type_Instance): Ensure that the actual of a
21718 synchronized formal derived type is a synchronized tagged type.
21719 (Instantiate_Formal_Package): When creating the instantiation used to
21720 validate the actual package of a formal declared without a box, check
21721 whether the formal itself depends on a prior actual.
21722 (Instantiate_Formal_Subprogram): Create new entities for the defining
21723 identifiers of the formals in the renaming declaration, for ASIS use.
21724 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
21725 a renaming declaration or a subtype declaration for an actual in an
21726 instance, capture location information of declaration in generic, for
21727 ASIS use.
21728 (Instantiate_Formal_Package): Add comments on needed additional tests.
21729 AI-317 (partial parametrization) is fully implemented.
21730 (Validate_Private_Type_Instance): Add check for actual which
21731 must have preelaborable initialization
21732 Use new // insertion for some continuation messages
21733 (Analyze_Formal_Object_Declaration): Change usage of Expression to
21734 Default_Expression. Add type retrieval when the declaration has an
21735 access definition. Update premature usage of incomplete type check.
21736 (Check_Access_Definition): New subsidiary routine. Check whether the
21737 current compilation version is Ada 05 and the supplied node has an
21738 access definition.
21739 (Instantiate object): Alphabetize local variables. Handle the creation
21740 of new renaming declarations with respect to the kind of definition
21741 used - either an access definition or a subtype mark. Guard against
21742 unnecessary error message in the context of anonymous access types after
21743 they have been resolved. Add check for required null exclusion in a
21744 formal object declaration.
21745 (Switch_View): A private subtype of a non-private type needs to be
21746 switched (the base type can have been switched without its private
21747 dependents because of the last branch of Check_Private_View.
21748 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
21749 value from BT.
21750 (Instantiate_Type): Emit an error message whenever a class-wide type of
21751 a tagged incomplete type is used as a generic actual.
21752 (Find_Actual_Type): Extend routine to handle a component type in a child
21753 unit that is imported from a formal package in a parent.
21754 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
21755 agree on constrainedness, rather than checking against ultimate ancestor
21756 (Instantiate_Subprogram_Body): Create a cross-reference link to the
21757 generic body, for navigation purposes.

21762 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
21763 type.
21764 (New_Stream_Subprogram): When processing an attribute definition clause
21765 for a stream-oriented subprogram, record an entity node occurring at
21766 the point of clause to use for checking the visibility of the clause,
21767 as defined by 8.3(23) as amended by AI-195.
21768 (New_Stream_Subprogram): New procedure, factoring behaviour from both
21769 New_Stream_Function and New_Stream_Procedure.
21770 (New_Stream_Function, New_Stream_Procedure): Removed.

21777
21778 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
21779 generate the same errors compiling under -gnatc.
21780 (Try_Object_Operation): If no candidate interpretation succeeds, but
21781 there is at least one primitive operation with the right name, report
21782 error in call rather than on a malformed selected component.
21783 (Analyze_Selected_Component): If the prefix is an incomplete type from
21784 a limited view, and the full view is available, use the full view to
21785 determine whether this is a prefixed call to a primitive operation.
21786 (Operator_Check): Verify that a candidate interpretation is a binary
21787 operation before checking the type of its second formal.
21788 (Analyze_Call): Add additional warnings for function call contexts not
21789 yet supported.
21790 (Analyze_Allocator): Move the check for "initialization not allowed for
21791 limited types" after analyzing the expression. This is necessary,
21792 because OK_For_Limited_Init looks at the structure of the expression.
21793 Before analysis, we don't necessarily know what sort of expression it
21794 is. For example, we don't know whether F(X) is a function call or an
21795 indexed component; the former is legal in Ada 2005; the latter is not.
21796 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
21797 were missing. We also didn't handle qualified expressions. Now also
21798 allow function calls. Use new common routine OK_For_Limited_Init.
21799 (Analyze_Type_Conversion): Do not perform some legality checks in an
21800 instance, because the error message will be redundant or spurious.
21801 (Analyze_Overloaded_Selected_Component): Do not do style check when
21802 setting an entity, since we do not know it is the right entity yet.
21803 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
21804 (Analyze_Overloaded_Selected_Component): Same change
21805 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
21806 since regular incomplete subtypes are transformed into corresponding
21807 subtypes of their full views.
21808 (Complete_Object_Operation): Treat name of transformed subprogram call
21809 as coming from source, for browsing purposes.
21810 (Try_Primitive_Operation): If formal is an access parameter, compare
21811 with base type of object to determine whether it is a primitive
21812 operation.
21813 (Operator_Check): If no interpretation of the operator matches, check
21814 whether a use clause on any candidate might make the operation legal.
21815 (Try_Class_Wide_Operation): Check whether the first parameter is an
21816 access type whose designated type is class-wide.

21823 warn on infinite loops.
21824 Add \\ to some continuation messages
21825 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
21826 (Process_Bounds): If the bounds are integer literals that result from
21827 constant-folding, and they carry a user-defined type, preserve that type
21828 rather than treating this as an integer range.
21829 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
21830 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
21831 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
21832 left hand side of assignment.
21833 (Analyze_Assignment): Add suport to manage assigments to the attribute
21834 priority of a protected object.
21835 (Check_Possible_Current_Value_Condition): Allow fully qualified names
21836 not just identifiers.
21837 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
21838 or AND THEN for possible tracking.
21839 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
21840 case of while loops so we can track values in the loop body.

AC		 21846 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
21847 procedure cannot be a protected operation (it is a basic_declaration,
21848 not a subprogram_declaration).
21849 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
21850 Subp. Add logic for entry processing.
21851 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
21852 Determine whether an entry or subprogram of a protected or task type
21853 override an inherited primitive of an implemented interface.
21854 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
21855 Update the actual used in calls to Check_Overriding_Indicator.
21856 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
21857 generate the proper reference to the parent unit, for cross-reference.

21859 Is_Formal.
21860 Add -gnatd.l --Use Ada 95 semantics for limited function returns,

21862 entity, scope, and name suffix, and handle setting of the new
21863 Extra_Formals field.
21864 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
21865 pass new parameters. Add support for adding the new extra access formal
21866 for functions whose calls are treated as build-in-place.
21867 (Analyze_A_Return_Statement): Correct casing in error message.
21868 Move Pop_Scope to after Analyze_Function_Return, because an extended
21869 return statement really is a full-fledged scope. Otherwise, visibility
21870 doesn't work right. Correct use of "\" for continuation messages.
21871 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
21872 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
21873 the node doesn't get properly marked as analyzed.
21874 (Analyze_Subprogram_Body): If subprogram is a function that returns
21875 an anonymous access type that denotes a task, build a Master Entity
21876 for it.
21877 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
21878 proper usage of null exclusion in a result definition.
21879 (Process_Formals): Code cleanup and new error message.
21880 (Process_Formals): Detect incorrect application of null exclusion to
21881 non-access types.
21882 (Conforming_Types): Handle conformance between [sub]types and itypes
21883 generated for entities that have null exclusions applied to them.
21884 (Maybe_Primitive_Operation): Add an additional type retrieval when the
21885 base type is an access subtype. This case arrises with null exclusions.
21886 (New_Overloaded_Entity): Do not remove the overriden entity from the
21887 homonym chain if it corresponds with an abstract interface primitive.
21888 (Process_Formals): Replace membership test agains Incomplete_Kind with a
21889 call to the synthesized predicate Is_Incomplete_Type.
21890 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
21891 primitives.
21892 (Analyze_Subprogram_Declaration): Check that abstract interface
21893 primitives are abstract or null.
21894 (Analyze_Subprogram_Specification): Remove previous check for abstract
21895 interfaces because it was not complete.

21904 may have only a limited view.
21905 (Analyze_Package_Specification): For the private part of a nested
21906 package, install private_with_clauses of enclosing compilation unit if
21907 we are in its visible part.
21908 (Declare_Inherited_Private_Subprograms): Complete barrier
21909 to ensure that the primitive operation has an alias to some parent
21910 primitive. This is now required because, after the changes done for the
21911 implementation of abstract interfaces, the contents of the list of
21912 primitives has entities whose alias attribute references entities of
21913 such list of primitives.
21914 (Analyze_Package_Specification): Simplify code that handles parent units

21933 implementation defined attribute Stub_Type (simply let the analysis of

21943 in a formal object declaration or in a subtype declaration.
21944 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
21945 (Check_Null_Exclusion): New local routine to

21947 profile of a renamed subprogram have required null exclusions when
21948 their counterparts of the renaming already impose them.

23653 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
23654 Adjust call is for a newly-allocated object. In that case we must not
23655 assume that the finalization list chain pointers are correct (since they
23656 come from a bit-for-bit copy of the original object's pointers) so if

23678 (Expand_Call): An indirect call through an access parameter of a
23679 protected operation is not a protected call.
23680 Add circuit to raise CE in Ada 2005 mode following call
23681 to Raise_Exception.
23682 (Register_DT_Entry): Do nothing if
23683 the run-time does not give support to abstract interfaces.
23684 (Freeze_Subprogram): In case of dispatching operations, do not generate
23685 code to register the operation in the dispatch table if the source
23686 is compiled with No_Dispatching_Calls.
23687 (Register_Predefined_DT_Entry): Generate code that calls the new

23689 Set_Prim_Op_Address.

23691 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
23692 on array assignments if the right-hand side is a function call that has
23693 been inlined. Check is performed on the assignment in the block.
23694 (Process_Bounds): If bounds and range are overloaded, apply preference
23695 rule for root operations to disambiguate, and diagnose true ambiguity.
23696 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
23697 a tag-indeterminate right-hand side even when Expander_Active is True.
23698 Needed to ensure that dispatching calls to T'Input are allowed and
23699 get the tag of the target class-wide object.
23700
23701 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
23702 an inherited primitive operation that already overrides several
23703 abstract interface primitives. For transitivity, the new entity must
23704 also override all the abstract interface primitives covered by the
23705 inherited overriden primitive.
23706 Emit warning if new entity differs from homograph in same scope only in
23707 that one has an access parameter and the other one has a parameter of
23708 a general access type with the same designated type, at the same
23709 position in the signature.
23710 (Make_Inequality_Operator): Use source locations of parameters and
23711 subtype marks from corresponding equality operator when creating the
23712 tree structure for the implicit declaration of "/=". This does not
23713 change anything in behaviour except that the decoration of the
23714 components of the subtree created for "/=" allows ASIS to get the
23715 string images of the corresponding identifiers.
23716 (Analyze_Return_Statement): Remove '!' in warning message.
23717 (Check_Statement_Sequence): Likewise.
23718 (Analyze_Subprogram_Body): For an access parameter whose designated type
23719 is an incomplete type imported through a limited_with clause, use the
23720 type of the corresponding formal in the body.
23721 (Check_Returns): Implicit return in No_Return procedure now raises
23722 Program_Error with a compile time warning, instead of beging illegal.
23723 (Has_Single_Return): Function returning unconstrained type cannot be
23724 inlined if expression in unique return statement is not an identifier.
23725 (Build_Body_To_Inline): It is possible to inline a function call that
23726 returns an unconstrained type if all return statements in the function
23727 return the same local variable. Subsidiary procedure Has_Single_Return
23728 verifies that the body conforms to this restriction.
23729
23730 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
23731 same type, and one of them is of an anonymous access type, convert
23732 the other operand to it, so that this is a valid binary operation for
23733 gigi.
23734 (Resolve_Type_Conversion): Handle subtypes of protected types and
23735 task types when accessing to the corresponding record type.
23736 (Resolve_Allocator): Add '\' in 2-line warning message.
23737 Remove '!' in warning message.
23738 (Resolve_Call): Add '\' in 2-line warning message.
23739 (Valid_Conversion): Likewise.
23740 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
23741 resulting type may be an access type with an implicit dereference.
23742 Obtain the proper component from the designated type.
23743 (Make_Call_Into_Operator): Handle properly a call to predefined equality
23744 given by an expanded name with prefix Standard, when the operands are
23745 of an anonymous access type.
23746 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
23747 Explicit_Dereference and Resolve_Selected_Component, to verify that the
23748 prefix of the expression is not of an incomplete type. Allows full
23749 diagnoses of all semantic errors.
23750 (Resolve_Actuals): If the actual is an allocator whose directly
23751 designated type is a class-wide interface we build an anonymous
23752 access type to use it as the type of the allocator. Later, when
23753 the subprogram call is expanded, if the interface has a secondary
23754 dispatch table the expander will add a type conversion to force
23755 the displacement of the pointer.
23756 (Resolve_Call): If a function that returns an unconstrained type is
23757 marked Inlined_Always and inlined, the call will be inlined and does
23758 not require the creation of a transient scope.
23759 (Check_Direct_Boolean_Op): Removed
23760 (Resolve_Comparison_Op): Remove call to above
23761 (Resolve_Equality_Op): Remove call to above
23762 (Resolve_Logical_Op): Inline above, since this is only call.

23764 convertible anonymous access types.

23814 point to some memory that is associated with some other object. In
23815 addition, remove all the old code that generated the assignments
23816 associated with the signature of the dispatch table and replace them
23817 by a call to the new subprogram Set_Signature.
23818 (Set_All_DT_Position): Change the algorithm because now we have a
23819 separate dispatch table associated with predefined primitive operations.

23821 add explicit dereference to get access to the object after the call

24048 call, since the attribute, which must be 'Input, can never be abstract.
24049 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
24050 call to the Input attribute (even when rewritten).
24051 (Propagate_Tag): Augment comment to indicate the possibility of a call
24052 to an Input attribute.

24111 Detect and warn on redundant with clauses detected in a package spec
24112 and/or body when -gnatwr is used.
24113 (Analyze_Context): Analyze config pragmas before other items
24114 (Install_Context_Items): Don't analyze config pragmas here
24115 (Install_Limited_Withed_Unit): Set limited entity of package in
24116 with_clause so that cross-reference information or warning messages on
24117 unused packages can be properly generated
24118 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
24119 has Error_Posted set. Prevent infinite loops in illegal programs.
24120 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
24121 to the point of the error test requiring the current unit to be private.
24122 This ensures that private with clauses are not exempted from the basic
24123 checking for being a descendant of the same library unit parent as a
24124 withed private descendant unit.
24125 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
24126 handle private with clauses properly, as well as to account for cases
24127 where the withed unit is a public descendant of a private ancestor
24128 (in which case the current unit must be a descendant of the private
24129 ancestor's parent). The spec comments were updated accordingly. Also,
24130 the old error message in this subprogram was replaced with error
24131 messages that mirror the errors tested and reported by
24132 Check_Private_Child_Unit.
24133 Parameter and variable names improved for readability.
24134 (Install_Limited_Context_Clauses): Remove test for a withed unit being
24135 private as the precondition for calling
24136 Check_Private_Limited_Withed_Unit since that subprogram has been
24137 revised to test public units as well as private units.

24146 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
24147 were not always properly handled previously.
24148 (Formal_Entity): Complete rewrite, to handle properly some complex case
24149 with multiple levels of parametrization by formal packages.
24150 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
24151 to the corresponding derived type declaration for proper semantics.

24154 (Check_Component): Enforce restriction on components of
24155 unchecked_unions: a component in a variant cannot contain tasks or
24156 controlled types.
24157 (Unchecked_Union): Allow nested variants and multiple discriminants, to
24158 conform to AI-216.
24159 Add pragma Ada_2005 (synonym for Ada_05)
24160 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
24161 were not always properly handled previously.
24162 Document that pragma Propagate_Exceptions has no effect
24163 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
24164 (Set_Convention_From_Pragma): Check that if a convention is
24165 specified for a dispatching operation, then it must be
24166 consistent with the existing convention for the operation.
24167 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
24168 longer required to specify an vtable-ptr component in the record. For
24169 compatibility reasons we leave the support for the previous definition.
24170 (Analyze_Pragma, case No_Return): Allow multiple arguments
24171
24172 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
24173 non-overrideen inherited operation with a controlling result as
24174 illegal only its implicit declaration comes from the derived type
24175 declaration of its result's type.
24176 (Check_Possible_Deferred_Completion): Relocate the object definition
24177 node of the subtype indication of a deferred constant completion rather
24178 than directly analyzing it. The analysis of the generated subtype will
24179 correctly decorate the GNAT tree.
24180 (Record_Type_Declaration): Check whether this is a declaration for a
24181 limited derived record before analyzing components.
24182 (Analyze_Component_Declaration): Diagnose record types not explicitly
24183 declared limited when a component has a limited type.
24184 (Build_Derived_Record_Type): Code reorganization to check if some of
24185 the inherited subprograms of a tagged type cover interface primitives.
24186 This check was missing in case of a full-type associated with a private
24187 type declaration.
24188 (Constant_Redeclaration): Check that the subtypes of the partial and the
24189 full view of a constrained deferred constant statically match.
24190 (Mentions_T): A reference to the current type in an anonymous access
24191 component declaration must be an entity name.
24192 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
24193 class_wide type to refer to full type, not to the incomplete one.
24194 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
24195 available. Required to give support to the certified run-time.
24196 (Analyze_Component_Declaration): In case of anonymous access components
24197 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
24198 (Process_Discriminants): For an access discriminant, use the
24199 discriminant specification as the associated_node_for_itype, to
24200 simplify accessibility checks.

242022006-02-13 Ed Schonberg <schonberg@adacore.com>
24203 Javier Miranda <miranda@adacore.com>
24204
24205 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
24206 abstract interpretations on an operator, remove interpretations that
24207 yield Address or a type derived from it, if one of the operands is an
24208 integer literal.
24209 (Try_Object_Operation.Try_Primitive_Operation,
24210 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
24211 location when creating the new reference to a primitive or class-wide
24212 operation as a part of rewriting a subprogram call.
24213 (Try_Primitive_Operations): If context requires a function, collect all
24214 interpretations after the first match, because there may be primitive
24215 operations of the same type with the same profile and different return
24216 types. From code reading.
24217 (Try_Primitive_Operation): Use the node kind to choose the proper
24218 operation when a function and a procedure have the same parameter
24219 profile.
24220 (Complete_Object_Operation): If formal is an access parameter and prefix
24221 is an object, rewrite as an Access reference, to match signature of
24222 primitive operation.
24223 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
24224 by an expanded name with prefix Standard, when the operands are of an
24225 anonymous access type.
24226 (Remove_Abstract_Operations): If the operation is abstract because it is
24227 inherited by a user-defined type derived from Address, remove it as
24228 well from the set of candidate interpretations of an overloaded node.
24229 (Analyze_Membership_Op): Membership test not applicable to cpp-class
24230 types.
24231
242322006-02-13 Bob Duff <duff@adacore.com>
24233
24234 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
24235 redundant use clauses.
24236 In particular, if the scope of two use clauses overlaps, but one is not
24237 entirely included in the other, we should not warn. This can happen
24238 with nested packages.
24239 (Analyze_Subprogram_Renaming): Protect the compiler against previously
24240 reported errors. The bug was reported when the compiler was built
24241 with assertions enabled.
24242 (Find_Type): If the node is a 'Class reference and the prefix is a
24243 synchronized type without a corresponding record, return the type
24244 itself.
24245
242462006-02-13 Javier Miranda <miranda@adacore.com>
24247
24248 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
24249 if this is the full-declaration associated with a private declaration
24250 that implement interfaces, then the private type declaration must be
24251 limited.
24252 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
24253 as aliased. The use of the 'access attribute is not available for such
24254 object (for this purpose the object should be explicitly marked as
24255 aliased, but being an anonymous type this is not possible).

24267
24268 * sem_type.adb (Write_Overloads): Improve display of candidate
24269 interpretations.
24270 (Add_One_Interp): Do not add to the list of interpretations aliased
24271 entities corresponding with an abstract interface type that is an
24272 immediate ancestor of a tagged type; otherwise we have a dummy
24273 conflict between this entity and the aliased entity.
24274 (Disambiguate): The predefined equality on universal_access is not
24275 usable if there is a user-defined equality with the proper signature,
24276 declared in the same declarative part as the designated type.
24277 (Find_Unique_Type): The universal_access equality operator defined under
24278 AI-230 does not cover pool specific access types.
24279 (Covers): If one of the types is a generic actual subtype, check whether
24280 it matches the partial view of the other type.
24281

24311 Integer'Value("- 5") and Integer'Value("-+5") now correctly
24312 raise Constraint_Error.
24313
24314 * s-vallli.adb (Scan_Long_Long_Integer): Call
24315 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
24316 do not scan leading blanks and sign twice.
24317 Integer'Value("- 5") and Integer'Value("-+5") now correctly

24319
24320 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
24321 Scan_Long_Long_Unsigned): Split out most of the processing from
24322 Scan_Long_Long_Unsigned out into
24323 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
24324 This prevents scanning leading blanks and sign twice.
24325 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
24326 See RM-3.5(44).
24327
24328 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split

aedc2c2b
AC		 24534
24535 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
24536 link to the version that does nothing. This way the task termination
24537 routine is not executed twice for the environment task when finishing
24538 because of an unhandled exception.
24539
24540 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
24541 handler because of an unhandled exception.
24542
24543 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

24545
24546 * s-finimp.adb (initialization code): Modify the soft link for the
24547 finalization of the global list instead of Adafinal.
24548
24549 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
24550 non-tasking version of the soft link for task termination. We do
24551 nothing since if we are using the non-tasking version it
24552 means that the task termination functionality is not used.
24553 (Null_Finalize_Global_List): Add this null version for the procedure
24554 in charge of finalizing the global list for controlled objects.
24555 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
24556 instead for handling run-time termination in a more flexible way.
24557 (Adafinal_NT): This new procedure will take care of finalizing the
24558 global list for controlled objects if needed, but no tasking
24559 finalization.
24560
24561 * s-tarest.adb (Task_Lock): Do not try to lock again the
24562 Global_Task_Lock if we already own it. Otherwise, we get blocked in

24564 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
24565 until all nested locks have been released.
24566 (Task_Wrapper): Call the fall-back task termination handler. It
24567 applies to all tasks but the environment task.
24568 (Finalize_Global_Tasks): Add the call for the task termination
24569 procedure for the environment task.
24570 (Task_Wrapper): suppress warnings around declaration of
24571 Secondary_Stack_Address.

24577 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
24578 Common_ATCB record.
24579
24580 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
24581 Fall_Back_Handler, and Specific_Handler.
24582
24583 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
24584 defined in Ada.Task_Termination, to avoid circular dependencies.
24585 (Termination_Handler): Redefine this type here, alredy defined in
24586 Ada.Task_Termination, for avoiding circular dependencies.
24587 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
24588 for storing task termination handlers. In addition,
24589 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
24590 Common_ATCB because it is used by both the regular and the restricted
24591 run times.
24592 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
24593 Common_ATCB because it is used by both the regular and the restricted
24594 run times.

24596
24597 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
24598 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

24600 tasks but the environment task.
24601 (Finalize_Global_Tasks): Call the task termination procedure for the
24602 environment task. The call to Finalize_Global_List is now performed
24603 using the soft links mechanism.

24606 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
24607 potentially blocking operations has been moved from
24608 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
24609 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
24610 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
24611 this run-time check.
24612
24613 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
24614 of task termination procedure.
24615 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

24656
24657 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
24658 to the specification because the frontend generates code that uses this
24659 subprogram.
24660 (Set_Interface_Table): Add missing assertion.
24661 Update documentation describing the run-time structure.
24662 (Displace): New subprogram that displaces the pointer to the object
24663 to reference one of its secondary dispatch tables.
24664 (IW_Membership): Modified to use the new table of interfaces.
24665 (Inherit_TSD): Modified to use the new table of interfaces.
24666 (Register_Interface_Tag): Use the additional formal to fill the
24667 contents of the new table of interfaces.
24668 (Set_Interface_Table): New subprogram that stores in the TSD the
24669 pointer to the table of interfaces.

24682
24683 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
24684 in all the calls to Expand_Interface_Thunk. Instead of referencing the
24685 record component containing the tag of the secondary dispatch table we
24686 have to use the Offset_To_Top run-time function to get this information;
24687 otherwise if the pointer to the base of the object has been displace
24688 we get a wrong value if we use the 'position attribute.
24689
24690 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
24691 all the calls to Expand_Interface_Thunk.
24692 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

24701 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
24702 Get_Tagged_Kind and Set_Tagged_Kind.
24703 (Tagged_Kind): New function that determines the tagged kind of a type
24704 with respect to limitedness and concurrency and returns a reference to
24705 RE_Tagged_Kind.

24726 RE_TK_Tagged, RE_TK_Task.
24727
24728 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
24729 Init_Secondary_Tags_Internal to allow its use with interface types and
24730 also to generate the code for the new additional actual required
24731 by Set_Offset_To_Top.
24732 (Build_Init_Statements): In case of components associated with abstract
24733 interface types there is no need to generate a call to its IP.
24734 (Freeze_Record_Type): Generate Select Specific Data tables only for
24735 concurrent types.

24737 the bodies and specifications of the predefined primitive operations
24738 dealing with dispatching selects and abort, 'Callable, 'Terminated only

25021 Ada 95) and, in the case of Ada 2005, to check that the user-specified
25022 attributes are visible at the point of the subprogram declaration.

25297 deal with different cases of static and dynamic elaboration checks (all
25298 checks does not count in the first case, but does in the second).
25299 (Expr_Known_Valid): Do not assume that the result of any arbitrary
25300 function call is valid, since this is not the case.
25301 (Ensure_Valid): Do not apply validity check to a real literal
25302 in a universal or fixed context
25303
25304 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
25305 elementary types using the operator in standard. It is cleaner not to
25306 modify the programmers intent, especially in the case of floating-point.
25307 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
25308 it did not matter because we always rewrote a/=b to not(a=b).
25309 (Expand_Allocator_Expression): For an allocator expression whose nominal
25310 subtype is an unconstrained packed type, convert the expression to its
25311 actual constrained subtype.
25312 Implement warning for <= or >= where < or > not possible
25313 Fix to Vax_Float tests (too early in many routines, causing premature
25314 Vax_Float expansions.
25315
25316 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
25317 to be used with packages and generic packages as well as with

25320 of pragma Suppress (All_Checks)
25321 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
25322 a string literal for precise control over warnings.
25323 Avoid raise of pragma in case of unrecognized pragma and just return
25324 instead.
25325
25326 * sem_prag.ads: Minor reformatting
25327
25328 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
25329 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

25331 Include -gnatwx as part of -gnatg (warn on redundant parens)
25332 Allow optional = after -gnatm
25333 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
25334 longer sets Elaboration_Checks.
25335 Code to set warning mode moved to Sem_Warn
25336 so that it can be shared by pragma processing.
25337
25338 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
25339 statement.

25446 deferral level, when abort is not allowed, to a later stage (the
25447 Task_Wrapper).
25448 (Task_Wrapper): If Abort is not allowed, reset the deferral level since
25449 it will not get changed by the generated code. It was previously done
25450 in Create_Task.
25451
254522005-11-14 Thomas Quinot <quinot@adacore.com>
25453 Olivier Hainque <hainque@adacore.com>

25458 from a fat or thin pointer type and a constrained object type.
25459 (annotate_value): Handle BIT_AND_EXPR.
25460 (annotate_rep): Don't restrict the back annotation of inherited
25461 components to the type_annotate_only case.
25462 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
25463 we are not defining the type.
25464 <E_Record_Type>: Likewise.
25465 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
25466 to get advantage of the new maybe_stabilize_reference interface, to
25467 ensure that what we reference is indeed stabilized instead of relying
25468 on assumptions on what the stabilizer does.
25469 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
25470 type imported through a limited_with clause, use its non-limited view.
25471 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
25472 differentiation.
25473 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
25474 of #if sections + explicit comparisons of convention identifiers.
25475 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
25476 before early-returning for certain types when code generation is
25477 disabled.
25478 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
25479 nullification of gnu_expr we do for objects with address clause and
25480 that we are not defining.
25481 (elaborate_expression_1): Do not create constants when creating
25482 variables needed by the debug info: the dwarf2 writer considers that
25483 CONST_DECLs is used only to represent enumeration constants, and emits
25484 nothing for them.
25485 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
25486 object with an address clause into an indirect reference, drop the
25487 initializing expression.
25488 Include "expr.h".
25489 (STACK_CHECK_BUILTIN): Delete.

25494 corresponding to the renamed object as ignored for debugging purposes.
25495
25496 * trans.c (tree_transform, case N_Attribute_Reference, case Attr_Size &
25497 related): For a prefix that is a dereference of a fat or thin pointer,
25498 if there is an actual subtype provided by the front-end, use that
25499 subtype to build an actual type with bounds template.
25500 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
25501 is provided by the front-end, use that subtype to compute the size of
25502 the deallocated object.
25503 (gnat_to_gnu): When adding a statement into an elaboration procedure,
25504 check for a potential violation of a No_Elaboration_Code restriction.
25505 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
25506 with extra arguments to control whether to recurse through non-values
25507 and to let the caller know if the stabilization has succeeded.
25508 (gnat_stabilize_reference): Now a simple wrapper around
25509 maybe_stabilize, for common uses without restriction on lvalues and
25510 without need to check for the success indication.
25511 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
25512 pass false instead of 0 as the FORCE argument which is a bool.
25513 (Identifier_to_gnu): Remove checks ensuring that an renamed object
25514 attached to a renaming pointer has been properly stabilized, as no such
25515 object is attached otherwise.
25516 (call_to_gnu): Invoke create_var_decl to create the temporary when the
25517 function uses the "target pointer" return mechanism.
25518 Reinstate conversion of the actual to the type of the formal
25519 parameter before any other specific treatment based on the passing
25520 mechanism. This turns out to be necessary in order for PLACEHOLDER
25521 substitution to work properly when the latter type is unconstrained.
25522
25523 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
25524 common pattern.
25525 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
25526 with extra arguments to control whether to recurse through non-values
25527 and to let the caller know if the stabilization has succeeded.
25528
25529 * utils2.c (gnat_build_constructor): Only sort the fields for possible
25530 static output of record constructor if all the components are constant.
25531 (gnat_build_constructor): For a record type, sort the list of field
25532 initializers in increasing bit position order.
25533 Factor common code to build a storage type for an unconstrained object
25534 from a fat or thin pointer type and a constrained object type.
25535 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
25536 types variants, and process special cases of VIEW_CONVERT expressions
25537 as their NOP_EXPR counterpart to ensure we get to the
25538 CORRESPONDING_VARs associated with CONST_DECls.
25539 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
25540 on the right-hand side.
25541
25542 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
25543 a common pattern.
25544 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
25545 are converting back to its original type.
25546 (convert) <JM input>: Fallthrough regular conversion code instead of
25547 extracting the object if converting to a type variant.
25548 (create_var_decl): When a variable has an initializer requiring code
25549 generation and we are at the top level, check for a potential violation
25550 of a No_Elaboration_Code restriction.
25551 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
25552 SIZE and SIZE_UNIT which we need for later back-annotations.
25553 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
25554 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
25555 is an unchecked union.
25556 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
25557 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
25558 main variant, just replace the VIEW_CONVERT_EXPR.

25560
25561 * repinfo.h, repinfo.ads: Add tcode for BIT_AND_EXPR.

25693
25694 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
25695 for task component, in the case of a limited aggregate. The enclosed
25696 object declaration will create it earlier. Otherwise, in the case of a
25697 nested aggregate, the object may appear in the wrong scope.
25698 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
25699 (Gen_Assign): If the component being assigned is an array type and the
25700 expression is itself an aggregate, wrap the assignment in a block to
25701 force finalization actions on the temporary created for each row of the
25702 enclosing object.
25703 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
25704 structures are initialized after all discriminants are set so that
25705 they can be accessed even when their offset is dynamic.

25710 * sem_attr.adb: Implement Machine_Rounding attribute
25711 (Analyze_Access_Attribute): The access attribute may appear within an
25712 aggregate that has been expanded into a loop.
25713 (Check_Task_Prefix): Add semantic check for attribute 'Callable and
25714 'Terminated whenever the prefix is of a task interface class-wide type.
25715 (Analyze_Attribute): Add semantic check for attribute 'Identity whenever
25716 the prefix is of a task interface class-wide type.
25717
25718 * s-vaflop-vms-alpha.adb: Valid_D, Valid_F, Valid_G: Make Val constant

25732
25733 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
25734 and related): For a prefix that is an explicit dereference of an
25735 access to unconstrained packed array type, annotate the dereference
25736 with an actual subtype so GIGI can make a correct size computation.
25737 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
25738 'Unrestricted_Access, if the designated type is an interface we
25739 add a type conversion to force the displacement of the pointer
25740 to the secondary dispatch table.
25741 Use Universal_Real instead of Long_Long_Float when we need a high
25742 precision float type for the generated code (prevents gratuitous
25743 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
25744 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
25745 'Terminated for task interface class-wide objects. Generate a call to
25746 the predefined dispatching routine used to retrieve the _task_id from
25747 a task corresponding record.
25748 (Expand_Fpt_Attribute): Major change to properly handle Vax_Float
25749
25750 * sem_disp.adb: Change name Is_Package to Is_Package_Or_Generic_Package

25764 Thomas Quinot <quinot@adacore.com>
25765
25766 * exp_ch5.adb (Expand_N_Assignment_Statement, Tagged_Case): For an
25767 assignment of a value of a tagged type that has been rewritten to a
25768 block statement, it is known by construction that no checks are
25769 necessary for the statements within the block: analyze it with checks
25770 suppressed.
25771 (Expand_N_If_Statement): When killing a dead then-branch in an
25772 if-statement that has elsif_parts, recompute the Current_Value node
25773 for any entity whose value is known from the condition of the first
25774 elsif_part.
25775 (Expand_N_Return_Statement): When returning a mutable record, convert
25776 the return value into its actual subtype in order to help the backend
25777 to return the actual size instead of the maximum. This is another
25778 aftermath of not returning mutable records on the sec-stack anymore.
25779
25780 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
25781 handling of error msg for suspicious reverse range iteration.
25782 (Check_Possible_Current_Value_Condition): Move declaration from body to
25783 spec, to allow this subprogram to be called from exp_ch5.

25786
25787 * exp_dist.adb (Append_Array_Traversal): Modify constrained case to

257912005-11-14 Pascal Obry <obry@adacore.com>
25792
25793 * expect.c (__gnat_kill) [Win32]: Fix implementation, the pid returned
25794 by spawnve is a process handle, no need to convert. Add a parameter
25795 close to control wether the process handle must be closed.
25796 (__gnat_waitpid): Fix implementation, the pid returned by spawnve is
25797 a process handle, not need to convert.
25798 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.
25799
25800 * g-expect.adb: (Kill): Document the new close parameter.

25802 waitpid() is using it.
25803 (Send_Signal): Release the process handle.
25804
258052005-11-14 Robert Dewar <dewar@adacore.com>
25806
25807 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
25808 need a high precision float type for the generated code (prevents
25809 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
25810 used).
25811
25812 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we
25813 need a high precision float type for the generated code (prevents
25814 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
25815 used).
25816 (Expand_Width_Attribute): In configurable run-time, the attribute is not
25817 allowed on non-static enumeration subtypes. Force a load error to emit
25818 the correct diagnostic.

25823
25824 * exp_intr.adb (Expand_Unc_Deallocation): If GIGI needs an actual
25825 subtype to compute the size of the designated object at run-time,
25826 create such a subtype and store it in the Actual_Designated_Subtype
25827 attribute of the N_Free_Statement.
25828 Generate itype for classwide designated object in both cases of
25829 user-specified storage pool: specific and class-wide, not only in the
25830 specific case.
25831 Raise CE when trying to set a not null access type object to null.
25832 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
25833 an explicit loop, because freeze nodes make its position variable.

25841 Build_Stream_Procedure): Add the null-excluding attribute to the first
25842 formal.
25843 This has no semantic meaning under Ada95 mode but it is a
25844 requirement under Ada05 mode.
25845
25846 * par-ch3.adb (P_Access_Definition): Addition of warning message if
25847 the null exclusion is used under Ada95 mode
25848 (P_Null_Exclusion): The qualifier has no semantic meaning in Ada 95.

25862 subprogram body.
25863 (Freeze_Entity): Freeze the equivalent_type of an access_to_protected_
25864 subprogram whenever available.

26108 In addition some minor reorganization of the code has been done to
26109 leave it more clear.
26110 (Analyze_Type_Declaration): If type has previous incomplete tagged

26167 whose default is abstract because the object type itself is abstract.
26168 (Find_Type): If the type is incomplete and appears as the prefix of a
26169 'Class reference, it is tagged, and its list of primitive operations
26170 must be initialized properly.

26800 check on the level of the return expression of a class-wide function
26801 can be elided. The check usually isn't needed if the expression has a
26802 specific type (unless it's a conversion or a formal parameter). Also
26803 add a test for whether accessibility checks are suppressed. Augment

26939 expanded in the code that returns the value of the displaced actual.
26940 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
26941 conversions that have no effect in the generated code because no
26942 displacement is required. Code cleanup; use local variables to

27184 Javier Miranda <miranda@adacore.com>
27185
27186 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
27187 from object notation, the original node is unanalyzed and carries no
27188 semantic information, so that accessiblity checks must be performed on
27189 the type of the actual itself.

27191 compatibility with Build_Protected_Sub_Specification.
27192 (Check_Overriding_Inherited_Interfaces): Add suport to handle

27203
27204 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
27205 whether a potential circularity is harmless, because it includes units
27206 loaded through a limited_with clause. Extends previous treatment which
27207 did not handle properly arbitrary combinations of limited and
27208 non-limited clauses.

27243
27244 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
27245 position set is provided, we compute one in order to reduce the maximum
27246 length of the keys. This computation first selects a character
27247 position between 1 and the minimum length of the keys in order to
27248 avoid reducing one of the keys to an empty string.
27249 (Initialize, Compute): When the ratio V to K is too low, the algorithm
27250 does not converge. The initialization procedure now comes with a
27251 maximum number of iterations such that when exceeded, an exception is
27252 raised in Compute. The user can initialize this ratio to another value
27253 and try again
27254 Reformating and updated headers.

27258 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
27259 that given an entity T creates and returns an Itype that duplicates the
27260 contents of T. The returned Itype has the null-exclusion
27261 attribute set to True, and its Etype attribute references T
27262 to keep the association between the two entities.

27388 'Address attribute reference with an overloaded prefix, use the
27389 location of the prefix (not the location of the attribute reference) as
27390 the error location.
27391 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
27392 a function renaming thereof, is a valid prefix for 'Size (where it is
27393 intepreted as a function call).
27394 (Statically_Denotes_Entity): New predicate to determine whether the
27395 prefix of an array attribute can be considered static.
27396
27397 PR ada/9087

27410
27411 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
27412 become local to the whole package.
27413 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
27414 the package was already analyzed the new algorithm "replaces" the
27415 real entities by the shadow ones. This is required to ensure that
27416 the order of these entities in the homonym chains does not change;
27417 otherwise we can have undefined references at linking time because
27418 in case of conflicts the external name of the entities will have
27419 a suffix that depends on the order of the entities in the chain.
27420 (Remove_Limited_With_Clause): Complementary code that completes the
27421 new algorithm and replaces the shadow entities by the real ones.
27422 (Install_Limited_Withed_Unit): When unchaining entities before the
27423 installation of the shadow entities, only regular entities of the
27424 public part must be taken into account. This is required to
27425 keep this routine in synch with the work done by Remove_Limited_
27426 With_Clause
27427 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
27428 even if unit is analyzed, because the analysis of the unit is
27429 idempotent in any case, and the limited view of the unit may have to
27430 be installed for proper visibility.
27431 (Expand_Limited_With_Clause): Even if the unit in the implicit
27432 with_clause has been analyzed already, a limited view of the package
27433 must be built for the current context, if it does not exist yet.

27438
27439 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
27440 defining entity for the instance body, make a new defining identifier
27441 rather than copying the entity of the spec, to prevent accidental
27442 sharing of the entity list.
27443 (Check_Private_View): When exchanging views of private types, build the
27444 list of exchanged views as a stack, to ensure that on exit the exchanges
27445 are undone in the proper order.
27446 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
27447 Restore the compilation environment in case of instantiation_error.
27448 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
27449 for an anonymous access result.
27450 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition

27463
27464 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
27465 underlying type
27466 to check if a type is Constrained in cases related to code generation
27467 (rather than semantic checking) since otherwise we do not generate
27468 similar code for mutable private types depending if their
27469 discriminants are visible or not.
27470 (Check_Abstract_Overriding): Do not complain about failure to override
27471 the primitive operations used in dispatching selects since they will
27472 always be overriden at the freeze point of the type.
27473 (Access_Definition): Separate out handling for resetting the scope
27474 of an anonymous access function result type. Retrieve the scope
27475 of the associated function rather than using Current_Scope, which
27476 does not have a consistent value (depends on whether we're in the
27477 middle of analyzing formal parameters). Add ??? comment about
27478 finding a cleaner way to handle the special cases of scope setting.
27479 (Process_Incomplete_Dependents): A protected operation is never a
27480 dispatching operation (only its wrapper may be).
27481 (Build_Derived_Record_Type): In case of tagged private types that
27482 implement interfaces add derivation of predefined primitive
27483 operations.
27484 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
27485 by two parameters that are used in case of derivation from abstract
27486 interface types: No_Predefined_Prims is used to avoid the derivation
27487 of predefined primitives from the interface, and Predefined
27488 Prims_Only is used to complete the derivation predefined primitives
27489 in case of private tagged types implementing interfaces.
27490 Fix typo in comments
27491 (Find_Interface_In_Descendant): Protect the frontend against
27492 wrong code with large circularity chains.
27493 (Is_Private_Overriding): Add support for entities overriding interface
27494 subprograms. The test failed because Entities associated with overriden
27495 interface subprograms are always marked as hidden (and used to build
27496 the secondary dispatch table); in this case the overriden entity is
27497 available through the field abstract_interface_alias (cf. override_
27498 dispatching_operation)
27499 (Access_Definition): Set the scope of the type to Current_Scope for the
27500 case of a function with an anonymous access result type.
27501 (Access_Subprogram_Declaration): Handle creation of the type entity for
27502 an access-to-function type with an anonymous access result.
27503 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
27504 in handling for N_Access_Function_Definition.

27515 if required. Code cleanup.
27516 (Process_Subtype): Create the new null-excluding itype if
27517 required. Code cleanup.
27518 (Build_Derived_Record_Type): Code cleanup to avoid calling
27519 twice the subprogram derive_subprograms in case of private
27520 types that implement interfaces. In this particular case the
27521 subprogram Complete_Subprograms_Derivation already does the
27522 job associated with the second call.

27531 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
27532 V (Obj.F), the rewriting does not involve the indexed component, but
27533 only the selected component itself.
27534 Do not apply the transformation if the analyzed node is an actual of a
27535 call to another subprogram.
27536 (Complete_Object_Operation): Retain the entity of the
27537 dispatching operation in the selector of the rewritten node. The
27538 entity will be used in the expansion of dispatching selects.
27539 (Analyze_One_Call): Improve location of the error message associated
27540 with interface.
27541 (Analyze_Selected_Component): No need to resolve prefix when it is a
27542 function call, resolution is done when parent node is resolved, as
27543 usual.
27544 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
27545 when attempting to resolve a call transformed from its object notation.
27546 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
27547 of the argument list for each interpretation of the operation.
27548 (Try_Object_Operation): The designated type of an access parameter may
27549 be an incomplete type obtained through a limited_with clause, in which
27550 case the primitive operations of the type are retrieved from its full
27551 view.
27552 (Analyze_Call): If this is an indirect call, and the return type of the
27553 access_to_subprogram is incomplete, use its full view if available.

27557
27558 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
27559 access types the null-exclusion and access-to-constant attributes must
27560 also match.
27561 (Analyze_Return_Statement): When the result type is an anonymous access
27562 type, apply a conversion of the return expression to the access type
27563 to ensure that appropriate accessibility checks are performed.
27564 (Analyze_Return_Type): For the case of an anonymous access result type,
27565 generate the Itype and set Is_Local_Anonymous_Access on the type.
27566 Add ??? placeholder for check to disallow returning a limited object
27567 in Ada 2005 unless it's an aggregate or a result of a function call.
27568 Change calls from Subtype_Mark to Result_Definition.
27569 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
27570 Result_Definition in call to Make_Function_Specification.
27571 (Build_Body_To_Inline): Change Set_Subtype_Mark to
27572 Set_Result_Definition.
27573 (Make_Inequality_Operator): Change formal Subtype_Mark to
27574 Result_Definition in call to Make_Function_Specification.
27575 (Process_Formals): Create the new null-excluding itype if required.
27576 (New_Overloaded_Entity): For an entity overriding an interface primitive
27577 check if the entity also covers other abstract subprograms in the same
27578 scope. This is required to handle the general case, that is, overriding
27579 other interface primitives and overriding abstract subprograms inherited
27580 from some abstract ancestor type.
27581 (New_Overloaded_Entity): For an overriding entity that comes from
27582 source, note the operation that it overrides.
27583 (Check_Conformance, Type_Conformant): Addition of one new formal
27584 to skip controlling formals in the analysis. This is used to
27585 handle overloading of abstract interfaces.
27586 (Base_Types_Match): Add missing case for types imported from
27587 limited-with clauses
27588 (New_Overloaded_Entity): Add barrier to protect the use of
27589 the "alias" attribute.

27594 verify that the procedure and the entry are mode conformant.
27595 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
27596 as a different operator, which is often a cut-and-paste error.

27600
27601 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
27602 used in controlling parameters exclude null because it is necessary to
27603 read the tag to dispatch, and null has no tag.
27604 (Override_Dispatching_Operation): If the previous operation is inherited
27605 from an interface, it becomes hidden and does not participate in later
27606 name resolution.

27610 Gary Dismukes <dismukes@adacore.com>
27611
27612 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
27613 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
27614 the expander will generate the corresponding run-time check to evaluate
27615 the expression.
27616 (Resolve_Call): Check for legal type of procedure name or prefix that
27617 appears as a trigger in a triggering alternative.
27618 (Valid_Conversion): If expression is ambiguous and the context involves
27619 an extension of System, remove System.Address interpretations.
27620 (Resolve_Qualified_Expression): Reject the case of a specific-type
27621 qualification applied to a class-wide argument. Enhance comment
27622 to explain checking of Original_Node.
27623 (Resolve_Type_Conversion): The location of the error message was not
27624 general enough to handle the general case and hence it has been removed.
27625 In addition, this patch improves the text of the message.
27626 (Resolve_Type_Conversion): Add missing support for access to interface
27627 types.
27628 (Resolve_Type_Conversion): If the target is a class-wide interface type,
27629 do not expand if the expression is the actual in a call, because proper
27630 expansion will take place when the call itself is expanded.
27631 (Resolve_Allocator): If the context is an unchecked conversion, the
27632 allocator inherits its storage pool, if any, from the target type of
27633 the conversion.

276352005-09-01 Ed Schonberg <schonberg@adacore.com>
27636 Javier Miranda <miranda@adacore.com>
27637
27638 * sem_type.adb (Add_One_Interp): If a candidate operation is an
27639 inherited interface operation that has an implementation, use the
27640 implementation to avoid spurious ambiguities.
27641 (Interface_Present_In_Ancestor): In case of concurrent types we can't
27642 use the Corresponding_Record_Typ attribute to look for the interface
27643 because it is set by the expander (and hence it is not always
27644 available). For this reason we traverse the list of interfaces
27645 (available in the parent of the concurrent type).
27646 (Interface_Present_In_Ancestor): Handle entities from the limited view

276482005-09-01 Ed Schonberg <schonberg@adacore.com>
27649

27653 primitive procedure of a limited interface with a controlling first
27654 parameter.
27655 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
27656 of an entry.
27657 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
27658 capture if it is generated in the second operand of a short-circuit
27659 operation.
27660 Do not capture values for variables with address clauses.
27661 (Is_Object_Reference): Treat a function call as an object reference only
27662 if its type is not Standard_Void_Type.

28449 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
28450 longer protected objects. They have been replaced by lower-level
28451 suspension objects made up by a mutex and a condition variable (or
28452 their equivalent given a particular OS) plus some internal data to
28453 reflect the state of the suspension object.
28454 (Initialize, Finalize): Add this initialization procedure for
28455 Suspension_Object, which is a controlled type.
28456 (Finalize): Add the finalization procedure for Suspension_Object,
28457 which is a controlled type.
28458
28459 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
28460 Ada.Synchronous_Task_Control because there is no longer a need for a
28461 VxWorks specific version of this package. Target dependencies
28462 has been moved to System.Task_Primitives.Operations.
28463
28464 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
28465 longer needed.
28466 (InitializeCriticalSection, EnterCriticalSection,
28467 LeaveCriticalSection, DeleteCriticalSection): Replace the type
28468 pCriticalSection by an anonymous access type so that we avoid problems

28476 set the environment task mask here.
28477 (Current_State): Add this function that returns the state of the
28478 suspension object.
28479 (Set_False): Add this procedure that sets the state of the suspension
28480 object to False.
28481 (Set_True): Add this procedure that sets the state of the suspension
28482 object to True, releasing the task that was suspended, if any.
28483 (Suspend_Until_True): Add this procedure that blocks the calling task
28484 until the state of the object is True. Program_Error is raised if
28485 another task is already waiting on that suspension object.
28486 (Initialize): Add this procedure for initializing the suspension
28487 object. It initializes the mutex and the condition variable which are
28488 used for synchronization and queuing, and it sets the internal state
28489 to False.
28490 (Finalize): Add this procedure for finalizing the suspension object,
28491 destroying the mutex and the condition variable.

28497 which provides a low-level abstraction (using operating system
28498 primitives) for Ada.Synchronous_Task_Control.
28499 This object is made up by a mutex (for ensuring mutual exclusion), a
28500 condition variable (for queuing threads until the condition is
28501 signaled), a Boolean (State) indicating whether the object is open,
28502 and a Boolean (Waiting) reflecting whether there is a task already

28611
28612 * mlib-tgt-mingw.adb (Build_Dynamic_Library): Replace the previous
28613 implementation. This new version generates the proper DllMain routine
28614 to initialize the SAL. The DllMain is generated in Ada and compiled

28708 (Make_Abstract_Interface_DT): Minor code cleanup.
28709 (Set_All_DT_Position): Code cleanup. As part of the code cleanup
28710 this subprogram implements a new algorithm that provides the
28711 same functionality and it is more clear in case of primitives
28712 associated with abstract interfaces.
28713 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
28714 clean up, the functionality of this subprogram is now provided
28715 by Set_All_DT_Position.

28728 the object to give access to the interface tag associated with the
28729 secondary dispatch table.

28759 access component.
28760 (Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
28761 an access component in this context is a Local_Anonymous_Access, for
28762 proper accessibility checks.

28779 derivation if the derived type has an ancestor that is a formal type
28780 declared in the formal part of an enclosing generic.
28781 (Analyze_Object_Declaration): For protected objects, remove the check
28782 that they cannot contain interrupt handlers if not declared at library
28783 level.
28784 (Add_Interface_Tag_Components): New subprogram to add the tag components
28785 corresponding to all the abstract interface types implemented by a
28786 record type or a derived record type.

28801 Derived_Type_Declaration, Find_Type_Name, Inherit_Components,
28802 Process_Full_View, Record_Type_Declaration): Modified to give
28803 support to abstract interface types

28805 we are in the case of an abstact-interface derivation
28806 (Find_Type_Of_Subtype_Indic): Moved from the body of the package
28807 to the specification because it is requied to analyze all the

28811
28812 * exp_ch3.adb: Implement config version of persistent_bss pragma

28816 Make_Abstract_Interfaces_DT to generate the secondary tables
28817 associated with abstract interfaces.
28818 (Build_Init_Procedure): Modified to initialize all the tags
28819 corresponding.

28827 * exp_ch6.adb (Add_Simple_Call_By_Copy_Code): Handle properly an
28828 in-out parameter that is a component in an initialization procedure,
28829 whose constraint might depend on discriminants, and that may be
28830 misaligned because of packing or representation clauses.
28831 (Is_Legal_Copy): New predicate to determine whether a possibly
28832 misaligned in-out actual can actually be passed by copy/return. This
28833 is an error in case the type is by_reference, and a warning if this is
28834 the consequence of a DEC import pragma on the subprogram.
28835 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
28836 interface types
28837 (Expand_Inlined_Call): Mark temporary generated for the return value as
28838 internal, so that no useless scalar normalization is generated for it.
28839 (Expand_N_Subprogram_Declaration): Save unanalyzed body so calls to
28840 null procedure can always be inlined.
28841 (Expand_N_Subprogram_Declaration): If this is the declaration of a null
28842 procedure, generate an explicit empty body for it.
28843
28844 * exp_util.ads, exp_util.adb (Find_Interface_ADT): New subprogram.
28845 Given a type implementing an interface, returns the corresponding
28846 access_disp_table value.

28854 is a predefined primitive operation.
28855 (Expand_Subtype_From_Expr): If the expression is a selected component
28856 within an initialization procedure, compute its actual subtype, because

0adcdb66
AC		 28860 This package has been left available for compatibility with previous
28861 versions of the frontend. As part of the new layout this is now a
28862 dummy package that uses declarations available at a-tags.ads
28863
28864 * par-ch3.adb (P_Identifier_Declarations): Give an error for use of
28865 "constant access" and "aliased [constant] access" when not compiling
28866 with -gnat05.

28876 for a subprogram or instance declaration.
28877
28878 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Verify that an
28879 instantiation that is a dispatching operation has controlling access

28885 the generic that is created to represent the formal package.
28886 (Analyze_Package_Instantiation): Instantiate body immediately if the
28887 package is a predefined unit that contains inlined subprograms, and
28888 we are compiling for a Configurable_Run_Time.

28893 error message condition, null procedures are correctly detected now.
28894 (New_Overloaded_Entity): Bypass trivial overriding indicator check
28895 for subprograms in the context of protected types. Instead, the
28896 indicator is examined in Sem_Ch9 while analysing the subprogram
28897 declaration.
28898 (Check_Overriding_Indicator): Check consistency of overriding indicator
28899 on subprogram stubs as well.
28900 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
28901 the library level.

28903 the type of the first formal is a concurrent type, replace this type
28904 by the corresponding record type.
28905 (Analyze_Subprogram_Body): Undo the previous work.
28906 (Analyze_Procedure_Call): If the call has the form Object.Op, the
28907 analysis of the prefix ends up analyzing the call itself, after which
28908 we are done.
28909 (Has_Interface_Formals): New subprogram subsidiary to analyze
28910 subprogram_specification that returns true if some non
28911 class-wide interface subprogram is found
28912 (New_Overloaded_Entity): Modified to give support to abstract
28913 interface types
28914 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
28915 access to subprograms must be recursive.
28916 (Is_Unchecked_Conversion): Improve the test that recognizes
28917 instantiations of Unchecked_Conversion, and allows them in bodies that
28918 are to be inlined by the front-end. When the body comes from an
28919 instantiation, a reference to Unchecked_Conversion will be an
28920 Expanded_Name, even though the body has not been analyzed yet.
28921 Replace Is_Overriding and Not_Overriding in subprogram_indication with
28922 Must_Override and Must_Not_Override, to better express intent of AI.
28923 (Analyze_Subprogram_Body): If an overriding indicator is given, check
28924 that it is consistent with the overrinding status of the subprogram
28925 at this point.

28927 always inlined.
28928 If the subprogram is a null procedure, indicate that it does not need

28931 * sem_disp.adb (Check_Controlling_Type): Give support to entities
28932 available through limited-with clauses.
28933 (Check_Dispatching_Operation): A stub acts like a body, and therefore is
28934 allowed as the last primitive of a tagged type if it has no previous
28935 spec.
28936 (Override_Dispatching_Operation, Check_Dispatching_Operation): Modified
28937 to give support to abstract interface types
28938
28939 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
28940 in the case where the target type is an anonymous access type of an
28941 object or component (that is, when Is_Local_Anonymous_Access is true).
28942 Prevent the special checks for conversions of access discriminants in
28943 the case where the discriminant belongs to a nonlimited type, since
28944 such discriminants have their accessibility level defined in the same
28945 way as a normal component of an anonymous access type.
28946 (Resolve_Allocator): When an allocator's designated type is a class-wide
28947 type, check that the accessibility level of type given in the
28948 allocator's expression or subtype indication is not statically deeper

28956 types.
28957 (Valid_Tagged_Conversion): The conversion of a tagged type to an

28960 (Resolve_Actuals): Enable full error reporting on view conversions
28961 between unrelated by_reference array types.
28962 The rule for view conversions of arrays with aliased components is
28963 weakened in Ada 2005.
28964 Call to obsolescent subprogram is now considered to be a violation of
28965 pragma Restrictions (No_Obsolescent_Features).
28966 (Check_Direct_Boolean_Operator): If the boolean operation has been
28967 constant-folded, there is nothing to check.
28968 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
28969 check on possible violation of restriction No_Direct_Boolean_Operators
28970 until after expansion of operands, to prevent spurious errors when

31445 and Tok_Synchronized.
31446
31447 * sem_res.adb (Resolve_Actuals): Change error messages to refer to
31448 "dispatching" rather than "primitive" operations, since dispatching
31449 calls are now allowed to abstract formal subprograms (which are not
31450 primitive).
31451 Char_Literal_Value field is now a Uint
31452 (Resolve_Slice): If the prefix is an access to an unconstrained array,
31453 compute the actual subtype of the designated object to impose the proper
31454 index constraints.
31455 (Resolve_Selected_Component): Do not insert an access check if the
31456 prefix is an access type: such a node is expanded into an explicit
31457 dereference, on which the access check is performed anyway. Removes
31458 expensive duplicate checks.
31459 (Resolve_Call): Use new flag Is_Obsolescent and field
31460 Obsolescent_Warning so that pragma Obsolescent works on library
31461 subprograms.
31462 Add support for wide wide character type
31463 (Resolve_Allocator): Replace the error message on wrong null-exclusion
31464 value by a warning message.
31465 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
31466 as fixed-point, and one of the operands is non-static and universal, it
31467 can only be an illegal exponentiation operation, in which case there is
31468 no real value to retrieve.

31497 Corresponding_ Formal_Spec and simplify condition.

31503 (Eval_Arithmetic_Op): Check for compile time known signed integer
31504 overflow in the non-static case.
31505 (Subtypes_Statically_Match): A formal scalar type and its base type do
31506 not statically match.
31507
31508 * sem_util.adb (Collect_Primitive_Operations): Minor change of "/=" to
31509 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
31510 subtype).
31511 (Unit_Declaration_Node): Ditto.
31512 (Is_Variable_Prefix): For the case of an indexed component whose prefix
31513 has a packed array type, the prefix has been rewritten into a type

31518
31519 * stringt.ads, stringt.adb: Handle full UTF-32 range.
31520 Remove ["0A"] from comment, since it can look like a line terminator.
31521 Currently we don't permit this, but this is under discussion by the
31522 ARG, and it is easy enough to use a different example.
31523
31524 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
31525 handling UTF-32 encoding for wide wide character.

31532 bit range Add full UTF-32 support.
31533 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
31534 notify that constraint error will be raised at run-time
31535 because a null value is assigned to a null-excluding object.
31536 Remove some obsolete declarations and make Char_Code
31537 unsigned.
31538
31539 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
31540 corresponding to CE_Null_Not_Allowed, and adjust the output of all the

31544 wrong null-exclusion value by a warning message.
31545 (Enable_Range_Check): Do range check if the prefix is an
31546 explicit dereference whose designated object is an unconstrained array.
31547 Current algorithm for removing duplicate checks is over-eager in this
31548 case.

31551 null-exclusion value by a warning message

31562 Char_Literal_Value field is now a Uint.
31563
31564 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
31565 defined for subprogram renaming declarations. When set, the field
31566 indicates the defining entity of a corresponding formal subprogram
31567 when the renaming corresponds to a formal subprogram association in an
31568 instantiation.
31569 (Set_Corresponding_Formal_Spec): New procedure to return
31570 Corresponding_Formal_Spec field.
31571 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration

31574
31575 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
31576 pointer to the base of the dispatch table.
31577 Minor changes to comments.
31578 (Controlling_Type): New function for determining the tagged type
31579 associated with a tagged primitive subprogram.
31580 (Expand_Dispatching_Call): Add support for a controlling actual that is
31581 directly a value of type Ada.Tag rather than a tagged object.
31582
31583 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
31584 describing the new layout.
31585 (Dispatch_Table): The expander computes the actual array size, allocates
31586 the Dispatch_Table record accordingly, and generates code that displaces
31587 the base of the record after the Typeinfo_Ptr component. The access to
31588 these components is done by means of local functions.
31589 (Offset_To_Top): New function.
31590 (Typeinfo_Ptr): New function.
31591 (Get_TSD): Modified to access the new position of the TSD.

31598 * sem_ch12.adb: Add with and use for Sem_Disp.
31599 (Analyze_Associations): Minor change from "=" to "in" for use of
31600 N_Formal_Subtype_Declaration (which is now a subtype).
31601 (Set_Analyzed_Formal): Minor changes from "=" to "in" for uses of
31602 N_Formal_Subtype_Declaration (which is now a subtype).
31603 (Analyze_Formal_Subprogram): Add handling for
31604 N_Formal_Abstract_Subprogram, marking the formal as abstract and
31605 dispatching, setting the controlling status of the formal parameters
31606 and result, and issuing an error if there is no controlling type for
31607 the formal subprogram.
31608 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
31609 which is an unclean use of that field, we set the new field
31610 Corresponding_Formal_Spec to make the formal subprogram available to
31611 processing in Analyze_Subprogram_Declaration.
31612 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
31613 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
31614 Constrained, so that it is is does not statically match its anonymous
31615 base type.
31616
31617 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
31618 abstract formal subprograms in error check for functions returning
31619 abstract types. Set scope of new designator for
31620 a parameterless subprogram, so that it is available when checking the
31621 body for nested subprograms, before full analysis of said body.
31622 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
31623 subprogram only if inner one comes from source.
31624 (Analyze_Function_Call): If the call is given in object notation, the
31625 analysis of the name rewrites the node and analyzes it with the proper
31626 argument list. After analyzing the name, if the call has been rewritten
31627 and the result type is set, no further analysis is needed.
31628 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
31629 mark in function specification, in a context where the formals are
31630 visible and hide outer homographs.
31631
31632 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
31633 as the tagged type for the cases of abstract formal subprograms and
31634 renamings of those. Clean up spec comments.
31635 (Check_Dispatching_Context): Add error message to indicate "abstract
31636 procedure", covering the case of a call to a formal abstract procedure
31637 that has statically tagged operands.
31638 (Check_Dispatching_Call): Check for the case of an actual given by
31639 a tag-indeterminate function call whose type is an ancestor of the
31640 containing call's associated tagged type. This situation can occur
31641 for inherited primitives with function defaults. In this case we
31642 use the tagged type's tag directly as the controlling argument for
31643 the calls.
31644 (Expand_Call): Name change on call to Expand_Dispatch_Call.
31645
31646 * sprint.adb (Sprint_Node_Actual): Split
31647 N_Formal_Subprogram_Declaration into two alternatives for the new

33111 on the object if it is an entity or simple indexed component, to avoid
33112 spurious type errors.

33190 there is no use of GNAT.Sockets.Constants.
33191 Remove remaining pragma Import for C_Write
33192 Remove C_Read and C_Write from internal implementation unit
33193 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
33194 the read and write functions from the system runtime library is fine
33195 on UNIX but won't work under Windows).
33196
33197 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
33198 (Check_Selector): Use C_Recv instead of C_Read.
33199 Selectors are the GNAT.Sockets abstraction to perform a select()
33200 call on a set of descriptors. To allow abortion of an ongoing
33201 select operation, some data is written to a dedicated socket that
33202 is always monitored.
33203 Under Windows, the write and read library functions cannot operate
33204 on sockets, so we need to use send and recv instead, which is portable
33205 across all supported platforms.

33256 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
33257 sections were just mistakenly ignored. The former is
33258 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
33259 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
33260 of hpux. This prevents an unwanted definition of the symbol

33303 type only if the size is not greater than that of the packed array.

33319 be expandable in place even if the aggregate does not come from source.
33320 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
33321 designated object of an allocator in place, rather than building it
33322 first on the stack. The previous scheme forces a full copy of the array,
33323 and may be altogether unsusable if the size of the array is too large

33357 implementations of the Partition Communication Subsystem for the
33358 Distributed Systems Annex (DSA). The three available implementations
33359 are the dummy stub implementation (No_DSA), and two versions based on
33360 two different distribution runtime libraries: GARLIC and PolyORB. Both
33361 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution

33501
33502 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
33503 appear in the code for the main unit. Dependencies among units in the
33504 context of the main unit are established when those other units are
33505 compiled. Otherwise spurious elaboration constraints can generate

33512 subprogram is called with a parameter that is not an object name. This
33513 situation arises for some cases of illegal code, which is diagnosed
33514 later, and in this case it is wrong to call Is_Aliased, as that might
33515 cause a compiler crash.
33516 (Explain_Limited_Type): Refine previous fix to include
33517 inherited components of derived types, to provide complete information.

33523 modified to avoid checking the Aliased flag on entities that are not
33524 objects. (Checking that flag for non-objects is erroneous and could
33525 lead to a compiler crash).

34095 contains the required machinery for handling that.
34096
34097 * sem_util.ads: Change comment associated to procedure
34098 Check_Potentially_Blocking_Operation.
34099 This procedure does not insert a call for raising the exception because
34100 that is currently done by the run time.
34101
34102 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
34103
34104 * init.c: Add the global variable __gl_detect_blocking that indicates

34113
34114 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag

34116 Detect_Blocking active forces its effect in the whole partition.
34117
34118 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
34119 Detect_Blocking is active and delay is called from a protected

34134
34135 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
34136 (Register_Receiving_Stub): Add Subp_Info formal parameter.

34138 in distribution runtime library.
34139
34140 * sem_ch3.adb (Expand_Derived_Record): Rename to
34141 Expand_Record_Extension.
34142
34143 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
34144 primitive operations of potentially distributed object types that have
34145 non-controlling anonymous access formals.
34146
34147 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
34148 subprogram.
34149 New implementation of expansion for remote access-to-subprogram types,
34150 based on the RACW infrastructure.
34151 This version of sem_dist is compatible with PolyORB/DSA as well as
34152 GLADE.
34153
34154 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
34155 Asynchrronous that applies to a remote access-to-subprogram type, mark
34156 the underlying RACW type as asynchronous.
34157
34158 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
34159 __gnat_using_gnu_linker to 1.
34160
34161 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
34162 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
34163 GNAT.Perfect_Hash_Generators, and remove the empty
34164 GNAT.Perfect_Hash package.

34166 * atree.adb: Minor reformatting
34167
34168 * exp_ch3.adb (Expand_Derived_Record): Rename to
34169 Expand_Record_Extension.
34170 (Build_Record_Init_Proc.Build_Assignment): The default expression in
34171 a component declaration must remain attached at that point in the
34172 tree so New_Copy_Tree copies it if the enclosing record type is derived.
34173 It is therefore necessary to take a copy of the expression when building
34174 the corresponding assignment statement in the init proc.
34175 As a side effect, in the case of a derived record type, we now see the
34176 original expression, without any rewriting that could have occurred
34177 during expansion of the ancestor type's init proc, and we do not need
34178 to go back to Original_Node.
34179
34180 * exp_ch3.ads (Expand_Derived_Record): Rename to
34181 Expand_Record_Extension.
34182
34183 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

34185 type.
34186 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
34187 New subprograms. Used to create a proxy tagged object for a remote
34188 subprogram. The proxy object is used as the designated object
34189 for RAS values on the same partition (unless All_Calls_Remote applies).
34190 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
34191 System.Partition_Interface.Get_Unique_Remote_Pointer.
34192 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
34193 Renamed from Add_RAS_*_Attribute.
34194 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
34195 subprograms.
34196 New implementation of expansion for remote access-to-subprogram types,
34197 based on the RACW infrastructure.
34198
34199 * exp_dist.ads (Copy_Specification): Update comment to note that this
34200 function can copy the specification from either a subprogram
34201 specification or an access-to-subprogram type definition.
34202
342032004-09-09 Ed Schonberg <schonberg@gnat.com>
34204
34205 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
34206 in an instance, between an explicit subprogram an one inherited from a
34207 type derived from an actual.
34208
34209 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
34210 add a polling call if the subprogram is to be inlined by the back-end,
34211 to avoid repeated calls with multiple inlinings.
34212
34213 * checks.adb (Apply_Alignment_Check): If the expression in the address
34214 clause is a call whose name is not a static entity (e.g. a dispatching
34215 call), treat as dynamic.

35615 BIGGEST_ALIGNMENT.

364092004-06-07 Thomas Quinot <quinot@act-europe.fr>
36410
36411 * bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
36412 the index of the last element is Units.Last, not Units.Table'Last
36413 (which is usually not a valid index within the actually allocated
36414 storage for the table).
36415
36416 * exp_ch4.adb (Insert_Dereference_Action): Change predicate that
36417 determines whether to generate a call to a checked storage pool
36418 Dereference action.

36446
36447 * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
36448 includes case of a variable referenced on the left hand side of an
36449 assignment, therefore remove redundant code. Variables and prefixes of
36450 indexed or selected components are now marked as referenced on left
36451 hand side. Warnings are now properly emitted when variables or prefixes
36452 are assigned but not read.
36453
36454 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
36455 left hand side referenced variables. Private access types do not
36456 produce the warning "variable ... is assigned but never read".
36457 Add also additional checks to left hand side referenced variables.
36458 Aliased, renamed objects and access types do not produce the warning
36459 "variable ... is assigned but never read" since other entities may read
36460 the memory location.
36461
364622004-06-07 Jerome Guitton <guitton@act-europe.fr>
36463

36475 distinct from the operator appearing in the source, call appropriate
36476 routine to insert conversions when needed, and complete resolution of
36477 node.
36478 (Resolve_Intrinsic_Operator): Fix cut-and-paste bug on transfer of
36479 interpretations for rewritten right operand.
36480 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

36548 * sem_ch12.adb (Same_Instantiated_Constant): New name for
36549 Same_Instantiated_Entity.
36550 (Same_Instantiated_Variable): Subsidiary to

36552 formals that are obtained from a previous formal package.
36553 (Instantiate_Subprogram_Body): Emit proper error when
36554 generating code and the proper body of a stub is missing.
36555
36556 * sem_ch4.adb (Remove_Address_Interpretations): If the operation still
36557 has a universal interpretation, do the disambiguation here.
36558
36559 * exp_ch4.adb (Expand_N_Type_Conversion,
36560 Expand_N_Unchecked_Type_Conversion): Special handling when target type
36561 is Address, to avoid typing anomalies when Address is a visible integer
36562 type.
36563
36564 * exp_ch6.adb (Expand_N_Subprogram_Body): Use Is_Descendent_Of_Address
36565 to determine whether a subprogram should not be marked Pure, even when
36566 declared in a pure package.
36567
365682004-05-27 Jose Ruiz <ruiz@act-europe.fr>
36569
36570 * gnat_ugn.texi: Replace pragma Ravenscar by pragma Profile.

36574 Update the documentation about the Ravenscar profile, following the
36575 definition found in AI-249.
36576
36577 * sem_prag.adb: Use FIFO_Within_Priorities and Ceiling_Locking when
36578 setting the Profile (Ravenscar). This must be done in addition to

36593
36594 * sem_prag.adb (Sig_Flags): A Pragma_Unchecked_Union does not count as
36595 a significant reference. Warnings are now properly emitted when a
36596 discriminated type is not referenced.
36597
36598 * lib-xref.adb (Generate_Reference): A deferred constant completion,
36599 record representation clause or record type discriminant does not
36600 produce a reference to its corresponding entity. Warnings are now

36629 arguments X with a maximum relative error of T'Machine_Epsilon, for X
36630 in -2.0**32 .. 2.0**32.
36631 (Cos, Sin): Always reduce arguments of 1/4 Pi or larger, to prevent
36632 reduction by the processor, which only uses a 68-bit approximation of
36633 Pi.
36634 (Tan): Always reduce arguments and compute function either using
36635 the processor's fptan instruction, or by dividing sin and cos as needed.

36677 limited view by a package entity that references the first shadow
36678 entity plus the first shadow private entity (required for limited-
36679 private-with clause)
36680 (New_Internal_Shadow_Entity): Code cleanup.
36681 (Remove_Limited_With_Clause): Update the implementation to undo the
36682 new work carried out by Build_Limited_Views.

36886 Assert (False).

36922 will be made visible later, just before we analyze the private part of
36923 the package.
36924 (Check_Private_Child_Unit): Allow private_with clauses in public
36925 siblings.
36926 (Install_Siblings): Make visible the private entities of private-withed
36927 siblings.

36929 are compiling a package declaration and the Private_With_OK flag was
36930 not set by the caller. These declarations will be installed later,
36931 just before we analyze the private part of the package.
36932
36933 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
36934 during the evaluation of the expression that initializes the object,
36935 decorate it with the expected type to avoid cascade errors.
36936 Code cleanup.
36937
36938 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
36939 subprogram we have to install the private_with clauses after its
36940 specification has been analyzed (as documented in AI-262.TXT).
36941
36942 * sem_ch8.adb (Has_Private_With): New function. Determines if the
36943 current compilation unit has a private with on a given entity.
36944 (Find_Direct_Name): Detect the Beaujolais problem described in
36945 AI-262.TXT
36946
36947 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
36948 provides the functionality of the function Is_Ancestor that was
36949 previously available in sem_ch10. It has been renamed to avoid
36950 overloading.
36951
36952 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses

38456 as is done for non-private derived record types.
38457
38458 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
38459 Ada 2005 AI-310: an abstract non-dispatching operation is not a
38460 candidate interpretation in an overloaded call.
38461

38469 statement whose right-hand side is an inlined call, save a copy of the
38470 original assignment subtree to preserve enough consistency for
38471 Analyze_Assignment to proceed.
38472
38473 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
38474 complete assignment subtree which is now unnecessary, as the expansion
38475 of inlined call has been improved to preserve a consistent assignment
38476 tree. Note_Possible_Modification must be called only
38477 after checks have been applied, or else unnecessary checks will
38478 be generated.
38479
38480 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
38481 of explicit dereferences that do not Come_From_Source:
38482 - be selective on cases where we must go back to the dereferenced
38483 pointer (an assignment to an implicit dereference must not be
38484 recorded as modifying the pointer);
38485 - do not rely on Original_Node being present (Analyze_Assignment
38486 calls Note_Possible_Modification on a copied tree).

38489 that is never assigned is encountered, prefer '<pointer> may be null'

38795 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
38796 attribute reference does not denote a subtype, it can be any
38797 expression that has a classwide type, potentially after an implicit
38798 dereference. In particular, the prefix can be a view conversion for
38799 a classwide type (for which Is_Object_Reference holds), but it can
38800 also be a value conversion for an access-to-classwide type. In the
38801 latter case, there is an implicit dereference, and the original node

39239 (Expand_N_Slice): Same. Always do the rewriting, even for the case
39240 of non-packed slices, since the dereference action generated by
39241 expansion of the explicit dereference is needed in any case.
39242 (Expand_N_Selected_Component): When rewriting an implicit dereference,
39243 analyze and resolve the rewritten explicit dereference so it is seen
39244 by the expander.
39245 (Insert_Dereference_Action): This procedure is now called only for the
39246 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
39247 dereferences that do not come from source (including explicit

39249 recursively insert a check for the dereference nodes contained within
39250 the check.

40125 Let finish_record_type decide instead.
40126 Don't make a bitfield if the field is to be addressable.
40127 Always set a size for the field if the record is packed, to ensure the
40128 checks for bitfield creation are triggered.
40129 (finish_record_type): During last pass over the fields, clear
40130 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
40131 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P

40610 importing constant atomic/volatile objects.
40611 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
40612 unless explicit Pure_Function pragma given, to avoid insidious bug of
40613 call to non-pure imported function getting eliminated.

40632 Make Default_Secondary_Stack_Size a variable instead of a constant,
40633 so that it can be modified by the new -Dnnn bind switch.
40634
40635 * rtsfind.adb (Load_Fail): Give full error message in configurable
40636 run-time mode if all_errors mode is set. This was not done in the case
40637 of a file not found, which was an oversight.
40638 Note if secondary stack unit is used by compiler.
40639
40640 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
40641 ineffective elaborate all pragmas on non-visible packages (this
40642 happened when a renamed subprogram was called). Now the elaborate all
40643 always goes on the package containing the renaming rather than the one
40644 containing the renamed subprogram.
40645

40650 has an Etype that references an E_String_Literal.
40651 (Eval_String_Literal): Avoid assumption that N_String_Literal node
40652 always references an E_String_Literal_Subtype entity. This may not
40653 be true in the future.
40654
40655 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
40656 pragma location.

40673 -B is specified. Fail when there are only foreign mains in attribute
40674 Main of the project file and -B is not specified. Do not skip bind/link
40675 steps when -B is specified.

40720 based on the new naming scheme.
40721

40747 qualified expression. Note that qualified expressions may have to be
40748 checked when limited aggregates are implemented.
40749
40750 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
40751 pure, emit warning.

40814 subtype mark.

40932 to provide dummy versions of these libraries to match the appropriate

409422003-12-08 Javier Miranda <miranda@gnat.com>
40943
40944 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
40945 aggregate in the parent. Otherwise constants with limited aggregates
40946 are not supported. Add new formal to pass the component type (Ctype).
40947 It is required to call the corresponding IP subprogram in case of
40948 default initialized components.
40949 (Gen_Assign): In case of default-initialized component, generate a
40950 call to the IP subprogram associated with the component.
40951 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
40952 of aggregate with default initialized components.
40953 (Has_Default_Init_Comps): Improve implementation to recursively check
40954 all the present expressions.
40955
40956 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
40957 to indicate that the initialization call corresponds to a
40958 default-initialized component of an aggregate.
40959 In case of default initialized aggregate with tasks this parameter is
40960 used to generate a null string (this is just a workaround that must be
40961 improved later). In case of discriminants, this parameter is used to
40962 generate a selected component node that gives access to the discriminant
40963 value.
40964
40965 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
40966 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
40967 allocated aggregates with default-initialized components.

44777 referring concrete lexical entities (keywords, attribute names
44778 etc.), and @syntax for ARM grammar elements. Use @r for English
44779 text in comments. Use @emph for emphasis. Change "if-statements"
44780 etc. to "if statements" (without @samp). Break long lines. Make
44781 casing of section names consistent.
44782 (Identifiers): Use @samp markup for variable names.
44783 (Comments): Use @samp markup for comment characters. Line-end
44784 comments may follow any Ada code, not just statements. Fix
44785 misspelling of "Integer" as "integer".
44786 (Loop statements): Do not use variable name "I", use "J".
44787 (Subprogram Declarations): Document alignment.
44788 (Subprogram Bodies, Block statements): Document empty line before
44789 "begin".

AJ		 46569
46570 * types.ads (Get_Hex_String): Returns the hexadecimal representation
46571 for a word. This is currently used only for CRC. In previous version,
46572 the checksum was using a representation with all letter being
46573 upper-case. With the new implementation (using CRC) we do not remove
46574 the 32th bit of the CRC, so we can have an upper-case starting letter
46575 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
46576 It is ambigous since the CRC was optional and could be followed by
46577 options like EB, EE. So now this routines uses lower-case letter for
46578 the hexadecimal representation. Strange enough only lower case letters
cfac6e9f 46579 where checked in Scan_ALI (even if this was not a possible case).
