We do nothing since if we are using the non-tasking version it means that the task termination functionality is not used. (Null_Finalize_Global_List): Add this null version for the procedure in charge of finalizing the global list for controlled objects. (Null_Adafinal): Remove this procedure. Adafinal_NT has been created instead for handling run-time termination in a more flexible way. (Adafinal_NT): This new procedure will take care of finalizing the global list for controlled objects if needed, but no tasking finalization. * s-tarest.adb (Task_Lock): Do not try to lock again the Global_Task_Lock if we already own it. Otherwise, we get blocked in some run-time operations. (Task_Unlock): Do not try to actually unlock the Global_Task_Lock until all nested locks have been released.

(Task_Wrapper): Call the task termination handler. It applies to all tasks but the environment task. (Finalize_Global_Tasks): Call the task termination procedure for the environment task. The call to Finalize_Global_List is now performed using the soft links mechanism. (Task_Wrapper): added dynamic stack analysis. * s-tasuti.adb (Abort_Tasks): The code in charge of checking potentially blocking operations has been moved from System.Tasking.Stages.Abort_Tasks to this procedure. There can be direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass through System.Tasking.Stages.Abort_Tasks, and we do not want to miss this run-time check. * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version of task termination procedure. (Init_Tasking_Soft_Links): Install the task-safe version of the soft link for the task termination procedure. * bindusg.adb: (Bindusg): Added documentation for -u option. * bindgen.adb (Get_Main_Ada) Added handling of dynamic stack analysis.

(Get_Tagged_Kind, Set_Tagged_Kind): New bodies. * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual in all the calls to Expand_Interface_Thunk. Instead of referencing the record component containing the tag of the secondary dispatch table we have to use the Offset_To_Top run-time function to get this information; otherwise if the pointer to the base of the object has been displace we get a wrong value if we use the 'position attribute. * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in all the calls to Expand_Interface_Thunk. (Make_Secondary_DT): Secondary dispatch tables do not have a table of interfaces; hence the call to Set_Interface_Table was clearly wrong. (Collect_All_Interfaces): Modify the internal subprogram Collect to ensure that the interfaces implemented by the ancestors are placed at the header of the generated list. (Expand_Interface_Conversion): Handle the case in which the displacement associated with the interface conversion is not statically known. In this case we generate a call to the new run-time subprogram Displace. (Make_DT): Generate and fill the new table of interfaces. (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for Get_Tagged_Kind and Set_Tagged_Kind.

(Build_Init_Statements): In case of components associated with abstract interface types there is no need to generate a call to its IP. (Freeze_Record_Type): Generate Select Specific Data tables only for concurrent types. (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate the bodies and specifications of the predefined primitive operations dealing with dispatching selects and abort, 'Callable, 'Terminated only for concurrent types. * exp_sel.ads, exp_sel.adb: New files. * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body, Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle properly protected objects and attach handler in the case of the restricted profile.

(Image_Wide_Character): Add boolean parameter Ada_2005 to deal with annoying FFFE/FFFF inconsistency. 2005-12-09 Robert Dewar Javier Miranda Ed Schonberg * exp_util.ads, exp_util.adb (Is_Ref_To_Bit_Packed_Slice): Handle case of type conversion. (Find_Interface): New subprogram that given a tagged type and one of its component associated with the secondary table of an abstract interface type, return the entity associated with such abstract interface type. (Make_Subtype_From_Expr): If type has unknown discriminants, always use base type to create anonymous subtype, because entity may be a locally declared subtype or generic actual. (Find_Interface): New subprogram that given a tagged type and one of its component associated with the secondary table of an abstract interface type, return the entity associated with such abstract interface type. * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the conversion cannot be handled at compile time.

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

Code reformatting and comment clean ups. 2005-12-09 Vincent Celier * gnatcmd.adb (GNATCmd): GNAT CHECK accepts switch -U If GNAT CHECK is called with a project file, but with no source on the command line, call gnatcheck with all the compilable sources of the project. Take into account the new command Check, for gnatcheck. Treat as for other ASIS tools: take into account project, specific package Check and Compiler switches. For ASIS tools, add the switches in package Compiler for the invocation of the compiler. * prj-attr.adb: Add package Check and its attributes * vms_conv.ads (Command_Type): New command Check, for gnatcheck * vms_conv.adb (Initialize): Change Params of command Check to unlimited files.

For Ada 2005, the error message is modified to indicate that the type's stream attributes must be visible (again, only for -gnat05). 2005-12-09 Ed Schonberg * sem_ch12.adb (Subtypes_Match): Handle properly Ada05 arrays of anonymous access types. * sem_eval.adb (Subtypes_Statically_Match): Implement new rules for matching of anonymous access types and anonymous access to subprogram types. 'R'M 4.9.1 (2/2). 2005-12-09 Ed Schonberg * sem_ch4.adb (Remove_Abstract_Operations): Do not apply preference rule prematurely when operands are universal, remaining ambiguities will be removed during resolution.

(Build_Private_Derived_Type): The entity of the created full view of the derived type does not come from source. If after installing the private declarations of the parent scope the parent is still private, use its full view to construct the full declaration of the derived type. (Build_Derived_Record_Type): Relax the condition that controls the execution of the check that verifies that the partial view and the full view agree in the set of implemented interfaces. In addition, this test now only takes into account the progenitors. (Derive_Interface_Subprograms): No need to derive subprograms of ancestors that are interfaces.

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

Add VxWworks 6.x specific functions (only called from VxWorks 6 files). (VX_FP_TASK): Now a function, to handle differences between VxWorks 5 and 6. (Set_Time_Slice): New function, replacing kerneltimeSlice to share code between Vxworks 5 and 6. (taskLock, taskUnlock): Removeed, no longer used. * adaint.c: The wait.h header is not located in the sys directory on VxWorks when using RTPs. (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when using RTPs. (__gnat_dup): dup is available on Vxworks when using RTPs. (__gnat_dup2): dup2 is available on Vxworks when using RTPs. * cal.c: Use the header time.h for Vxworks 6.0 when using RTPs. * expect.c: The wait.h header is not located in the sys directory on VxWorks when using RTPs. 2005-09-01 Thomas Quinot * g-soccon-vms.adb: Renamed to g-soccon-vms.ads * g-soccon-vms.ads: Renamed from g-soccon-vms.adb * g-soccon.ads, g-soccon-tru64.ads, g-soccon-aix.ads, g-soccon-darwin.ads, g-soccon-irix.ads, g-soccon-hpux.ads, g-soccon-solaris.ads, g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads: Add new constants: IP_MULTICAST_IF SO_RCVTIMEO/SO_SNDTIMEO IOV_MAX * gen-soccon.c: Move all target-specific file inclusions and macro definitions to gsocket.h, in order to ensure that any C code in socket.c will see a set of constants that is consistent with the contents of g-soccon.ads. * gsocket.h: Code imported from gen-soccon.c: Move all target-specific file inclusions and macro definitions to gsocket.h, in order to ensure that any C code in socket.c will see a set of constants that is consistent with the contents of g-soccon.ads. This change also makes gen-soccon self-contained (removing dependencies upon GCC internal headers). * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX iovecs at a time.

(Analyze_Attribute, case 'Size): The name of an enumeration literal, or a function renaming thereof, is a valid prefix for 'Size (where it is intepreted as a function call). (Statically_Denotes_Entity): New predicate to determine whether the prefix of an array attribute can be considered static. PR ada/9087 (Eval_Attr): Fix failure to evaluate Component_Size for unconstrained arrays (resulted in wrong value in packed case, since back end cannot handle this case) 2005-09-01 Robert Dewar * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to error msgs for most common cases. Use new errout insertion char < (conditional warning) 2005-09-01 Javier Miranda Ed Schonberg * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to become local to the whole package. (Install_Limited_Withed_Unit): Instead of unchaining real entities if the package was already analyzed the new algorithm "replaces" the real entities by the shadow ones. This is required to ensure that the order of these entities in the homonym chains does not change; otherwise we can have undefined references at linking time because in case of conflicts the external name of the entities will have a suffix that depends on the order of the entities in the chain. (Remove_Limited_With_Clause): Complementary code that completes the new algorithm and replaces the shadow entities by the real ones. (Install_Limited_Withed_Unit): When unchaining entities before the installation of the shadow entities, only regular entities of the public part must be taken into account. This is required to keep this routine in synch with the work done by Remove_Limited_ With_Clause (Install_Limited_With_Clause): Introduce implicit limited_with_clause even if unit is analyzed, because the analysis of the unit is idempotent in any case, and the limited view of the unit may have to be installed for proper visibility. (Expand_Limited_With_Clause): Even if the unit in the implicit with_clause has been analyzed already, a limited view of the package must be built for the current context, if it does not exist yet. 2005-09-01 Ed Schonberg Javier Miranda Gary Dismukes * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the defining entity for the instance body, make a new defining identifier rather than copying the entity of the spec, to prevent accidental sharing of the entity list. (Check_Private_View): When exchanging views of private types, build the list of exchanged views as a stack, to ensure that on exit the exchanges are undone in the proper order. (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Restore the compilation environment in case of instantiation_error. (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity for an anonymous access result. (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition (Formal_Entity): Handle properly the case of a formal package that denotes a generic package renaming. 2005-09-01 Thomas Quinot * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the clause if the array aggregate is surrounded by parentheses. 2005-09-01 Cyrille Comar Gary Dismukes Ed Schonberg Javier Miranda * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the underlying type to check if a type is Constrained in cases related to code generation (rather than semantic checking) since otherwise we do not generate similar code for mutable private types depending if their discriminants are visible or not. (Check_Abstract_Overriding): Do not complain about failure to override the primitive operations used in dispatching selects since they will always be overriden at the freeze point of the type. (Access_Definition): Separate out handling for resetting the scope of an anonymous access function result type. Retrieve the scope of the associated function rather than using Current_Scope, which does not have a consistent value (depends on whether we're in the middle of analyzing formal parameters). Add ??? comment about finding a cleaner way to handle the special cases of scope setting. (Process_Incomplete_Dependents): A protected operation is never a dispatching operation (only its wrapper may be). (Build_Derived_Record_Type): In case of tagged private types that implement interfaces add derivation of predefined primitive operations. (Derive_Subprograms): Replace the Is_Interface_Derivation parameter by two parameters that are used in case of derivation from abstract interface types: No_Predefined_Prims is used to avoid the derivation of predefined primitives from the interface, and Predefined Prims_Only is used to complete the derivation predefined primitives in case of private tagged types implementing interfaces. Fix typo in comments (Find_Interface_In_Descendant): Protect the frontend against wrong code with large circularity chains. (Is_Private_Overriding): Add support for entities overriding interface subprograms. The test failed because Entities associated with overriden interface subprograms are always marked as hidden (and used to build the secondary dispatch table); in this case the overriden entity is available through the field abstract_interface_alias (cf. override_ dispatching_operation) (Access_Definition): Set the scope of the type to Current_Scope for the case of a function with an anonymous access result type. (Access_Subprogram_Declaration): Handle creation of the type entity for an access-to-function type with an anonymous access result. (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition in handling for N_Access_Function_Definition. (Analyze_Subtype_Declaration): Modify the text of error message. (Derived_Type_Declaration): Modify the text of error message. (Process_Subtype): Modify the text of error message plus cleanup of one redundant error message. (Analyze_Component_Declaration): Code cleanup. (Analyze_Object_Declaration): Code cleanup. (Analyze_Subtype_Declaration): Propagate the null-exclusion attribute in case of access types. Code cleanup. (Array_Type_Declaration): Code cleanup. (Process_Discriminants): Create the new null-excluding itype if required. Code cleanup. (Process_Subtype): Create the new null-excluding itype if required. Code cleanup. (Build_Derived_Record_Type): Code cleanup to avoid calling twice the subprogram derive_subprograms in case of private types that implement interfaces. In this particular case the subprogram Complete_Subprograms_Derivation already does the job associated with the second call. * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit conversion to the full view when generating an operation for a discriminant whose type may currently be private. 2005-09-01 Ed Schonberg Javier Miranda * sem_ch4.adb (Transform_Object_Operation): In a context off the form V (Obj.F), the rewriting does not involve the indexed component, but only the selected component itself. Do not apply the transformation if the analyzed node is an actual of a call to another subprogram. (Complete_Object_Operation): Retain the entity of the dispatching operation in the selector of the rewritten node. The entity will be used in the expansion of dispatching selects. (Analyze_One_Call): Improve location of the error message associated with interface. (Analyze_Selected_Component): No need to resolve prefix when it is a function call, resolution is done when parent node is resolved, as usual. (Analyze_One_Call): Add a flag to suppress analysis of the first actual, when attempting to resolve a call transformed from its object notation. (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies of the argument list for each interpretation of the operation. (Try_Object_Operation): The designated type of an access parameter may be an incomplete type obtained through a limited_with clause, in which case the primitive operations of the type are retrieved from its full view. (Analyze_Call): If this is an indirect call, and the return type of the access_to_subprogram is incomplete, use its full view if available. 2005-09-01 Javier Miranda Gary Dismukes * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous access types the null-exclusion and access-to-constant attributes must also match. (Analyze_Return_Statement): When the result type is an anonymous access type, apply a conversion of the return expression to the access type to ensure that appropriate accessibility checks are performed. (Analyze_Return_Type): For the case of an anonymous access result type, generate the Itype and set Is_Local_Anonymous_Access on the type. Add ??? placeholder for check to disallow returning a limited object in Ada 2005 unless it's an aggregate or a result of a function call. Change calls from Subtype_Mark to Result_Definition. (Analyze_Subprogram_Body): Change formal Subtype_Mark to Result_Definition in call to Make_Function_Specification. (Build_Body_To_Inline): Change Set_Subtype_Mark to Set_Result_Definition. (Make_Inequality_Operator): Change formal Subtype_Mark to Result_Definition in call to Make_Function_Specification. (Process_Formals): Create the new null-excluding itype if required. (New_Overloaded_Entity): For an entity overriding an interface primitive check if the entity also covers other abstract subprograms in the same scope. This is required to handle the general case, that is, overriding other interface primitives and overriding abstract subprograms inherited from some abstract ancestor type. (New_Overloaded_Entity): For an overriding entity that comes from source, note the operation that it overrides. (Check_Conformance, Type_Conformant): Addition of one new formal to skip controlling formals in the analysis. This is used to handle overloading of abstract interfaces.

(Resolve_Type_Conversion): Add missing support for access to interface types. (Resolve_Type_Conversion): If the target is a class-wide interface type, do not expand if the expression is the actual in a call, because proper expansion will take place when the call itself is expanded.

(Interface_Present_In_Ancestor): In case of concurrent types we can't use the Corresponding_Record_Typ attribute to look for the interface because it is set by the expander (and hence it is not always available).

(Complete_Subprograms_Derivation): New subprogram used to complete type derivation of private tagged types implementing interfaces. In this case some interface primitives may have been overriden with the partial-view and, instead of re-calculating them, they are included in the list of primitive operations of the full-view. (Build_Derived_Record_Type): Modified to give support to private types implemening interfaces. (Access_Definition): Reject ALL on anonymous access types. (Build_Derived_Record_Type): In the case of Ada 2005, allow a tagged type derivation to occur at a deeper accessibility level than the parent type. For the case of derivation within a generic body however, disallow the derivation if the derived type has an ancestor that is a formal type declared in the formal part of an enclosing generic.

Given a type implementing an interface, returns the corresponding access_disp_table value. (Find_Interface_Tag): New subprogram. Given a type implementing an interface, returns the record component containing the tag of the interface. (Find_Interface_Tag): New overloaded subprogram. Subsidiary to the previous ones that return the corresponding tag and access_disp_table entities. (Is_Predefined_Dispatching_Operation): Determines if a subprogram is a predefined primitive operation.

When the body comes from an instantiation, a reference to Unchecked_Conversion will be an Expanded_Name, even though the body has not been analyzed yet. Replace Is_Overriding and Not_Overriding in subprogram_indication with Must_Override and Must_Not_Override, to better express intent of AI.

(Override_Dispatching_Operation, Check_Dispatching_Operation): Modified to give support to abstract interface types * sem_res.adb (Valid_Conversion): Perform an accessibility level check in the case where the target type is an anonymous access type of an object or component (that is, when Is_Local_Anonymous_Access is true). Prevent the special checks for conversions of access discriminants in the case where the discriminant belongs to a nonlimited type, since such discriminants have their accessibility level defined in the same way as a normal component of an anonymous access type. (Resolve_Allocator): When an allocator's designated type is a class-wide type, check that the accessibility level of type given in the allocator's expression or subtype indication is not statically deeper than the level of the allocator's access type.

(Stream_Attribute_Available): In Ada 95 mode, a stream attribute is treated as available for a limited private type if there is an attribute_definition_clause that applies to its full view, but not in other cases where the attribute is available for the full view (specifically, the sole fact that the full view is non-limited does not make the attribute available for the partial view). (Build_Access_Subprogram_Type): Diagnose attempt to apply 'access to a non-overloaded intrinsic subprogram. (Check_Stream_Attribute): Reject an attribute reference for an unavailable stream attribute even if the prefix is not a limited type (case of a 'Input attribute reference for an abstract, non-classwide type) (Stream_Attribute_Available): New function to determine whether a stream attribute is available at a place.

This adjustment was previously done in the MD_FALLBACK_FRAME_STATE_FOR, but it is more reliable to do that in the signal handler itself. (__gnat_install_handler) i386-linux: Set SA_SIGINFO in the sigaction flags, so that the handler is passed the context structure to adjust prior to the raise.
