+
+ * a-taster.ads, a-taster.adb: New files.
+
+ * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
+ link to the version that does nothing. This way the task termination
+ routine is not executed twice for the environment task when finishing
+ because of an unhandled exception.
+
+ * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
+ handler because of an unhandled exception.
+
+ * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
+ System.Tasking.Utilities instead of that in System.Tasking.Stages.
+
+ * s-finimp.adb (initialization code): Modify the soft link for the
+ finalization of the global list instead of Adafinal.
+
+ * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
+ non-tasking version of the soft link for task termination. 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.

+ defined in Ada.Task_Termination, to avoid circular dependencies.
+ (Termination_Handler): Redefine this type here, alredy defined in
+ Ada.Task_Termination, for avoiding circular dependencies.
+ (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
+ for storing task termination handlers. In addition,
+ Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
+ Common_ATCB because it is used by both the regular and the restricted
+ run times.
+ (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
+ Common_ATCB because it is used by both the regular and the restricted
+ run times.
+ (Common_ATCB): Added a dynamic task analyzer field.
+
+ * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
+ potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
+ (Task_Wrapper): Call the task termination handler. It applies to all
+ tasks but the environment task.

+ (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

+ Hristian Kirtchev <kirtchev@adacore.com>
+
+ * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
+ to the specification because the frontend generates code that uses this

+ to reference one of its secondary dispatch tables.

+ (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

+ ensure that the interfaces implemented by the ancestors are placed
+ at the header of the generated list.

+ associated with the interface conversion is not statically known. In
+ this case we generate a call to the new run-time subprogram Displace.

+ Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
+ primary dispatch table for a type.
+ (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
+ secondary dispatch table respectively of a tagged type.

+ RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
+ RE_TK_Tagged, RE_TK_Task.
+
+ * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
+ Init_Secondary_Tags_Internal to allow its use with interface types and
+ also to generate the code for the new additional actual required
+ by Set_Offset_To_Top.
+ (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.

+ 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.
+ Move embeded package Select_Expansion_Utilities into a separate external
+ package.
+ (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
+ Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
+ (Build_K, Build_S_Assignment): New subprograms, part of the select
+ expansion utilities.
+ (Expand_N_Asynchronous_Select, Expand_N_Conditional_Entry_Call,
+ Expand_N_Timed_Entry_Call): Optimize expansion of select statements
+ where the trigger is a dispatching procedure of a limited tagged type.
+
+2005-12-09 Olivier Hainque <hainque@adacore.com>
+
+ * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand

+
+ * sem_prag.adb: Processing for new pragma Complete_Representation
+ (Analyze_Pragma, case Debug): Implement two argument form.
+
+ * par-prag.adb: Entry for new pragma Complete_Representation
+ (Prag, case Debug): Recognize two argument form of pragma Debug
+ New interface for Set_Style_Check_Options.
+
+ * sem_ch13.adb: Implement new pragma Complete_Representation.

+2005-12-09 Gary Dismukes <dismukes@adacore.com>
+
+ * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
+ available user-specified stream attributes on limited parameters to
+ also test the type directly rather than only its underlying type (for
+ Ada 95) and, in the case of Ada 2005, to check that the user-specified
+ attributes are visible at the point of the subprogram declaration.
+ For Ada 2005, the error message is modified to indicate that the
+ type's stream attributes must be visible (again, only for -gnat05).

+
+ * 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).

+
+ * sem_ch4.adb (Remove_Abstract_Operations): Do not apply preference
+ rule prematurely when operands are universal, remaining ambiguities
+ will be removed during resolution.
+ Code cleanup.
+
+ * sem_type.adb (Disambiguate): In Ada95 mode, discard interpretations
+ that are Ada 2005 functions.
+ (Has_Abstract_Interpretation): Subsidiary to
+ Remove_Conversions, to remove ambiguities caused by abstract operations
+ on numeric types when operands are universal.

+
+ * sem_ch6.adb (Analyze_Subprogram_Body): Properly check categorization
+ for case where spec is categorized.
+
+2005-12-09 Javier Miranda <miranda@adacore.com>
+
+ * sem_ch8.adb (Find_Type): In case of tagged types that are concurrent
+ types use the corresponding record type. This was not needed before
+ the implementation of Ada 2005 synchronized types because
+ concurrent types were never tagged types in Ada 95.
+
+2005-12-09 Ed Schonberg <schonberg@adacore.com>
+
+ * sem_ch9.adb (Analyze_Delay_Alternative, Analyze_Delay_Until): Use the
