-	Add support for parsing multiple array index types info, or
-	multiple inherited interfaces info. This information cannot be stored
-	in Xref_Entity_Record, which only supports a single instance of Tref_*,
-	and is therefore stored in the list of references instead. It has a

-	defaults to parsing the command line of the application. They were also
-	modified to properly handle cases where each of the argument does not
-	start at index 1 (which is always true for Ada.Command_Line, but not
-	when processing any Argument_List).
-	(Free): New subprogram
-	(Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,

-	(Switch_Parameter_Type): New enum, which clarifies the code. The extra

-	which makes the code more extensible eventually.
-	(Getopt, Full_Switch): When the switch was returned as part of the
-	special character '*', make sure it is prepended by the switch character
-	('-' in general), so that the application knows whether "foo" or "-foo"
-	was specified on the command line.

-	(Side_Effect_Free): A selected component of an access type that

-	value may be affected by a renaming.
-	(Expand_Subtype_From_Expr): For limited objects initialized with build
-	in place function calls, do nothing; otherwise we prematurely introduce

-	(Analyze_Allocator): Remove Mark_Allocator and its invocation.
-	(Process_Function_Call): use Next, rather than Next_Actual, to analyze
-	successive actuals before analyzing the call itself.
-	(Try_Primitive_Operation): A primitive operation is compatible with the
-	prefix if the prefix has a synchronized type and the type of the formal
-	is its corresponding record, as can be the case when the primitive
-	operation is declared outside of the body of the type.
-	(Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
-	perform homonym traversal, looking for class-wide operation matches
-	(formerly done in statements of Try_Class_Wide_Operation). Matches on

-	(Mark_Allocator): An allocator with a discriminant association parent is
-	a coextension.

-	When processing a primitive of a concurrent type which implements an
-	interface change the type of all controlling formals to that of the
-	corresponding record type.
-	(Check_Synchronized_Overriding): Relax the conditional logic when trying
-	to determine the tagged type to which a primitive belongs.
-	(Check_Conventions): Capture condition to ignore a primitive operation
-	(which is shared between the loop in Check_Conventions and the one in

-	controlling result when determining whether to add a BIP_Alloc_Form
-	formal and a BIP_Final_List formal to the function.

-	function so that code can be generated.
-	(Process_Formals): In case of access-subtype itype whose designated
-	type is also an itype (situation that happens now with access to
-	subprograms) we mark the access-type itype with the Has_Delayed_Freeze
-	attribute to avoid backend problems.
-	(Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
-	init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
-	anonymous types' designated types are same before testing
-	Subtypes_Statically_Match.
-	(Create_Extra_Formals): Test for a named access parameter that is a
-	controlling formal as an additional condition for adding an
-	accessibility level formal. This can occur in the subp type created for
-	dispatching calls in Expand_Dispatching_Call, and allows calling
-	Create_Extra_Formals from that procedure rather than special-casing the
-	extra formals there.
-	(Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
-	when the function has a controlling result.
-	(Check_Returns): Add much more knowledge of the optimization of local
-	raise statements to gotos, to retain proper warnings in this case.

-	before the return is executed.
-	(Gen_Assign): Do not generate a call to deep adjust routine if the

-	(Is_Local_Access_Discriminant): Removed.
-	(Rewrite_Coextension): New routine which rewrites a static coextension
-	as a temporary and uses its unrestricted access in the construction of

-	(Complete_Coextension_Finalization): New routine. Generate finalization
-	attachment calls to all delayed coextensions.
-	(Expand_N_Allocator): Call Complete_Coextension_Finalization whenever

-	If the current allocator is controlled, but also a coextension, delay

-	Rename local variable "Node" to "Nod" in order to avoid confusion with
-	"Elists.Node".
-	(Expand_Allocator_Expression): Call Adjust for initialized allocators of
-	limited types that are not inherently limited. Such an allocator is
-	illegal, but is generated by the expander for a return statement, to
-	copy the result onto the secondary stack. This is the only case where a
-	limited object can be copied. Generate code to displace the pointer
-	to the object if the qualified expression is a class-wide interface
-	object. Such displacement was missing and hence the copy of the object
-	was wrong.
-	(Apply_Accessibility_Check): Handle allocated objects initialized in

-	(Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
-	and Expand_Allocator_Expression. Allocating class-wide interface objects
-	this routine displaces the pointer to the allocated object to reference
-	the component referencing the corresponding secondary dispatch table.
-	Expand_Allocator_Expression): Add missing support to allocate class-wide
-	interface objects initialized with a qualified expression.
-	(Get_Allocator_Final_List): Test for an anonymous access type that is a

-	(Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
-	properly the case of a function whose return type is a limited
-	class-wide interface type. Modify the code of the accessibility
-	check to handle class-wide interface objects. In this case we need to
-	displace "this" to reference the primary dispatch table to get access
-	to the TSD of the object (to evaluate its accessibility level).
-	(Expand_N_Extended_Return_Statement): Test for a tagged result type
-	rather than a controlling result as one of the conditions for
-	generating tests of the implicit BIP_Alloc_Form formal. The
-	initialization assignment is also handled according to whether the
-	result is tagged instead of controlling.
-	In the case where the init assignment is inserted in the "then" part of
-	the allocation conditional, rewrite the target to be a dereference of
-	the implicit BIP_Object_Access formal.
-	If the returned value is unconstrained and created on the secondary
-	stack, mark the enclosing block and function so that the secondary
-	stack is not reclaimed on return.
-	Treat returns from functions with controlling results similarly to
-	returns from functions with unconstrained result subtypes.
-	If the object returned is unconstrained, and an allocator must be
-	created for it, analyze the allocator once the block for the extended
-	return is installed, to ensure that finalizable components
-	of the expression use the proper finalization list. Guard the call to
-	Move_Final_List with a check that there is something to finalize.
-	(Make_Tag_Ctrl_Assignment): Use "old" handling

-	object.
-	(Expand_Inline_Call): If an actual is a literal, and the corresponding

-	value.  If the return type is a limited interface, do not treat the
-	return value as Controlled.
-	(Is_In_Place_Function):  If the return type is a limited interface,
-	treat as returning in place. The actual returned object may not always
-	be limited, but the caller has to assume that it is returned in place.
-	(Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the

-	(Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged

-	(Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
-	rather than Is_Controlled and Has_Controlled_Component, since we want to
-	include class-wide result types in this treatment. Also test for a
-	controlling result, since that also requires passing a finalization
-	list.
-	(Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
-	even when the result subtype is constrained, to handle calls involving
-	controlling results.
-	(Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
-	is now called even when the result subtype is constrained, to handle

-	(Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
-	on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure

-	(Add_Return): Accomodate rewritten pattern from local raise to goto

-	and do the right thing here in that case.
-	(Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
-	and end of subprogram code.
-	(Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
-	support for primitives that are functions (without formals) with a

-	(Inherited_From_Formal): If the actual subtype has not generic parent

-	Is_RAS.
-	(Append_RACW_Bodies): New subprogram.

-	(Build_Subprogram_Receiving_Stubs, PolyORB):
-	 * Retrieve the extra formals parameters at the
-	   end of the parameter stream.
-	 * Use Move_Any_Value to write back out parameters

-	(TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,

-	with a call to Get_Any_Type.
-	(Copy_Specification): Do controlling formal type substitution based on
-	Is_Controlling_Formal flag, instead of caller-provided object type.
-	(Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
-	a RACW primitive operation, we might get a subprogram declaration for an
-	ancestor of the RACW designated type (not for the designated type
-	itself), in the case where this operation is inherited. In this case we
-	have no easy means of determining the original tagged type for which
-	the primitive was declared, so instead we now rely on
-	Copy_Specification to use the Is_Controlling_Formal flag to determine
-	which formals require type substitution.

-	expressions for a formal in object of a limited type.
-	(Instantiate_Object): Ditto.
-	(Check_Formal_Package_Instance): Skip entities that are formal objects,
-	because they were defaulted in the formal package and no check applies
-	to them.
-	(Check_Formal_Package_Instance): Extend conformance check to other
-	discrete types beyond Integer.
-	(Process_Default): Copy directly the unmatched formal. A generic copy
-	has already been performed in Analyze_Formal_Package.
-	(Analyze_Associations): If a formal subprogram has no match, check for
-	partial parametrization before looking for a default, to prevent

-	(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
-	not set the instantiation environment before analyzing the actuals.
-	Fixes regression on 8515-003 with implementation of AI-133.
-	Set_Instance_Env checks whether the generic unit is a predefined
-	unit, in which case the instance must be analyzed with the latest Ada

-	* sem_ch4.adb (Try_Primitive_Operation): The call is legal if the

-	(Analyze_Allocator): Collect all coextensions regardless of the context.
-	Whether they can be allocated statically is determined in exp_ch4.
-	(Analyze_Selected_Component): If the prefix is a limited view and the
-	non-limited view is available, use the non-limited one.
-	(Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
-	therefore illegal), suggest a qualified expression rather than a type
-	conversion, because a type conversion would be illegal in this context.
-	(Anayze_Allocator): Trace recursively all nested allocators so that all
-	coextensions are on the corresponding list for the root. Do no mark
-	coextensions if the root allocator is within a declaration for a stack-
-	allocated object, because the access discriminants will be allocated on
-	the stack as well.
-	(Analyze_Call): Remove restriction on calls to limited functions for the
-	cases of generic actuals for formal objects, defaults for formal objects
-	and defaults for record components.
-	(Analyze_Allocator): Before analysis, chain coextensions on the proper
-	element list. Their expansion is delayed until the enclosing allocator
-	is processed and its finalization list constructed.
-	(Try_Primitive_Operation): If the prefix is a concurrent type, looks
-	for an operation with the given name among the primitive operations of
-	the corresponding record type.
-	(Analyze_Selected_Component): If the prefix is a task type that
-	implements an interface, and there is no entry with the given name,
-	check whether there is another primitive operation (e.g. a function)
-	with that name.
-	(Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
-	properly the indexing of a function call written in prefix form, where
-	the function returns an array type, and all parameters of the function
-	except the first have defaults.
-	(Analyze_Equality_Op): If this is a call to an implicit inequality, keep
-	the original operands, rather than relocating them, for efficiency and
-	to work properly when an operand is overloaded.
-	(Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
-	Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
-	(Analyze_Selected_Component): If the prefix is a private extension, only
-	scan the visible components, not those of the full view.
-	(Try_Primitive_Operation): If the operation is a procedure, collect all
-	possible interpretations, as for a function, because in the presence of
-	classwide parameters several primitive operations of the type can match
-	the given arguments.

-
-	* g-awk.adb (Default_Session, Current_Session): Compile this file in

-
-	* g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005

-
-	* s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from

-	* sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
-	type is in the same category as type of context before applying check,
-	to prevent anomalies in instantiations.
-	(Resolve_Aggregate): Remove test for limited components in aggregates.
-	It's unnecessary in Ada 95, because if it has limited components, then
-	it must be limited. It's wrong in Ada 2005, because limited aggregates
-	are now allowed.
-	(Resolve_Record_Aggregate): Move check for limited types later, because
-	OK_For_Limited_Init requires its argument to have been resolved.
-	(Get_Value): When copying the component default expression for a
-	defaulted association in an aggregate, use the sloc of the aggregate
-	and not that of the original expression, to prevent spurious
-	elaboration errors, when the expression includes function calls.
-	(Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
-	were missing. We also didn't handle qualified expressions. Now also
-	allow function calls. Use new common routine OK_For_Limited_Init.
-	(Resolve_Extension_Aggregate): Minor fix to bad error message (started
-	with space can upper case letter).
-
-	* sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set

-	(Build_Discriminant_Constraints): Use updated form of
-	Denotes_Discriminant.
-	(Process_Subtype): If the subtype is a private subtype whose full view
-	is a concurrent subtype, introduce an itype reference to prevent scope
-	anomalies in gigi.
-	(Build_Derived_Record_Type, Collect_Interface_Primitives,
-	Record_Type_Declaration):  The functionality of the subprograms
-	Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
-	is now performed by a single routine.
-	(Build_Derived_Record_Type): If the type definition includes an explicit
-	indication of limitedness, then the type must be marked as limited here
-	to ensure that any access discriminants will not be treated as having
-	a local anonymous access type.
-	(Check_Abstract_Overriding): Issue a detailed error message when an
-	abstract subprogram was not overridden due to incorrect mode of its
-	first parameter.
-	(Analyze_Private_Extension_Declaration): Add support for the analysis of
-	synchronized private extension declarations. Verify that the ancestor is
-	a limited or synchronized interface or in the generic case, the ancestor
-	is a tagged limited type or synchronized interface and all progenitors
-	are either limited or synchronized interfaces.
-	Derived_Type_Declaration): Check for presence of private extension when
-	dealing with synchronized formal derived types.
-	Process_Full_View): Enchance the check done on the usage of "limited" by
-	testing whether the private view is synchronized.
-	Verify that a synchronized private view is completed by a protected or
-	task type.
-	(OK_For_Limited_Init_In_05): New function.
-	(Analyze_Object_Declaration): Move check for limited types later,
-	because OK_For_Limited_Init requires its argument to have been resolved.
-	Add -gnatd.l --Use Ada 95 semantics for limited function returns,
-	in order to alleviate the upward compatibility introduced by AI-318.
-	(Constrain_Corresponding_Record): If the constraint is for a component
-	subtype, mark the itype as frozen, to avoid out-of-scope references to
-	discriminants in the back-end.
-	(Collect_Implemented_Interfaces): Protect the recursive algorithm of
-	this subprogram against wrong sources.
-	(Get_Discr_Value, Is_Discriminant): Handle properly references to a
-	discriminant of limited type completed with a protected type, when the
-	discriminant is used to constrain a private component of the type, and
-	expansion is disabled.
-	(Find_Type_Of_Object): Do not treat a return subtype that is an
-	anonymous subtype as a local_anonymous_type, because its accessibility
-	level is the return type of the enclosing function.
-	(Check_Initialization): In -gnatg mode, turn the error "cannot
-	initialize entities of limited type" into a warning.
-	(OK_For_Limited_Init): Return true for generated nodes, since it
-	sometimes violates the legality rules.
-	(Make_Incomplete_Declaration): If the type for which an incomplete
-	declaration is created happens to be the currently visible entity,
-	preserve the homonym chain when removing it from visibility.
-	(Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
-	inherited subprograms.
-	(Access_Definition): If this is an access to function that is the return
-	type of an access_to_function definition, context is a type declaration
-	and the scope of the anonymous type is the current one.
-	(Analyze_Subtype_Declaration): Add the defining identifier of a regular
-	incomplete subtype to the set of private dependents of the original
-	incomplete type.
-	(Constrain_Discriminated_Type): Emit an error message whenever an
-	incomplete subtype is being constrained.
-	(Process_Incomplete_Dependents): Transform an incomplete subtype into a
-	corresponding subtype of the full view of the original incomplete type.
-	(Check_Incomplete): Properly detect invalid usage of incomplete types
-	and subtypes.

-	(Register_DT_Entry): Do nothing if
-	the run-time does not give support to abstract interfaces.

-	on array assignments if the right-hand side is a function call that has
-	been inlined. Check is performed on the assignment in the block.

-	rule for root operations to disambiguate, and diagnose true ambiguity.
-	(Analyze_Assignment): Propagate the tag for a class-wide assignment with
-	a tag-indeterminate right-hand side even when Expander_Active is True.
-	Needed to ensure that dispatching calls to T'Input are allowed and

-
-	* sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
-	an inherited primitive operation that already overrides several
-	abstract interface primitives. For transitivity, the new entity must
-	also override all the abstract interface primitives covered by the
-	inherited overriden primitive.
-	Emit warning if new entity differs from homograph in same scope only in
-	that one has an access parameter and the other one has a parameter of
-	a general access type with the same designated type, at the same
-	position in the signature.
-	(Make_Inequality_Operator): Use source locations of parameters and
-	subtype marks from corresponding equality operator when creating the
-	tree structure for the implicit declaration of "/=". This does not
-	change anything in behaviour except that the decoration of the
-	components of the subtree created for "/=" allows ASIS to get the
-	string images of the corresponding identifiers.
-	(Analyze_Return_Statement): Remove '!' in warning message.
-	(Check_Statement_Sequence): Likewise.
-	(Analyze_Subprogram_Body): For an access parameter whose designated type
-	is an incomplete type imported through a limited_with clause, use the
-	type of the corresponding formal in the body.
-	(Check_Returns): Implicit return in No_Return procedure now raises
-	Program_Error with a compile time warning, instead of beging illegal.
-	(Has_Single_Return):  Function returning unconstrained type cannot be
-	inlined if expression in unique return statement is not an identifier.
-	(Build_Body_To_Inline): It is possible to inline a function call that
-	returns an unconstrained type if all return statements in the function
-	return the same local variable. Subsidiary procedure Has_Single_Return
-	verifies that the body conforms to this restriction.
-
-	* sem_res.adb (Resolve_Equality_Op): If the operands do not have the

-	given by an expanded name with prefix Standard, when the operands are
-	of an anonymous access type.
-	(Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
-	Explicit_Dereference and Resolve_Selected_Component, to verify that the
-	prefix of the expression is not of an incomplete type. Allows full
-	diagnoses of all semantic errors.
-	(Resolve_Actuals): If the actual is an allocator whose directly
-	designated type is a class-wide interface we build an anonymous
-	access type to use it as the type of the allocator. Later, when
-	the subprogram call is expanded, if the interface has a secondary
-	dispatch table the expander will add a type conversion to force
-	the displacement of the pointer.
-	(Resolve_Call): If a function that returns an unconstrained type is
-	marked Inlined_Always and inlined, the call will be inlined and does
-	not require the creation of a transient scope.
-	(Check_Direct_Boolean_Op): Removed
-	(Resolve_Comparison_Op): Remove call to above
-	(Resolve_Equality_Op): Remove call to above
-	(Resolve_Logical_Op): Inline above, since this is only call.

-	convertible anonymous access types.
-
-	PR ada/25885
-	(Set_Literal_String_Subtype): If the lower bound is not static, wrap

-	(Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for

-	(Make_DT, Make_Secondary_DT): If the tagged type has no user defined
-	primitives we reserve one dummy entry to ensure that the tag does not
-	point to some memory that is associated with some other object. In
-	addition, remove all the old code that generated the assignments
-	associated with the signature of the dispatch table and replace them
-	by a call to the new subprogram Set_Signature.
-	(Set_All_DT_Position): Change the algorithm because now we have a
-	separate dispatch table associated with predefined primitive operations.
-	(Expand_Interface_Conversion): In case of non-static offset_to_top
-	add explicit dereference to get access to the object after the call
-	to displace the pointer to the object.

-
-	* sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
-	abstract interpretations on an operator, remove interpretations that
-	yield Address or a type derived from it, if one of the operands is an
-	integer literal.
-	(Try_Object_Operation.Try_Primitive_Operation,
-	Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
-	location when creating the new reference to a primitive or class-wide
-	operation as a part of rewriting a subprogram call.
-	(Try_Primitive_Operations): If context requires a function, collect all
-	interpretations after the first match, because there may be primitive
-	operations of the same type with the same profile and different return
-	types. From code reading.
-	(Try_Primitive_Operation): Use the node kind to choose the proper
-	operation when a function and a procedure have the same parameter
-	profile.
-	(Complete_Object_Operation): If formal is an access parameter and prefix
-	is an object, rewrite as an Access reference, to match signature of
-	primitive operation.
-	(Find_Equality_Type, Find_One_Interp): Handle properly equality given
-	by an expanded name with prefix Standard, when the operands are of an
-	anonymous access type.
-	(Remove_Abstract_Operations): If the operation is abstract because it is
-	inherited by a user-defined type derived from Address, remove it as
-	well from the set of candidate interpretations of an overloaded node.
-	(Analyze_Membership_Op): Membership test not applicable to cpp-class
-	types.
-
-2006-02-13  Bob Duff  <duff@adacore.com>
-
-	* sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
-	redundant use clauses.
-	In particular, if the scope of two use clauses overlaps, but one is not
-	entirely included in the other, we should not warn.  This can happen
-	with nested packages.
-	(Analyze_Subprogram_Renaming): Protect the compiler against previously
-	reported errors. The bug was reported when the compiler was built
-	with assertions enabled.
-	(Find_Type): If the node is a 'Class reference and the prefix is a
-	synchronized type without a corresponding record, return the type
-	itself.
-
-2006-02-13  Javier Miranda  <miranda@adacore.com>
-
-	* sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
-	if this is the full-declaration associated with a private declaration
-	that implement interfaces, then the private type declaration must be
-	limited.
-	(Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
-	as aliased. The use of the 'access attribute is not available for such
-	object (for this purpose the object should be explicitly marked as
-	aliased, but being an anonymous type this is not possible).

-	* sem_type.adb (Write_Overloads): Improve display of candidate
-	interpretations.
-	(Add_One_Interp): Do not add to the list of interpretations aliased
-	entities corresponding with an abstract interface type that is an
-	immediate ancestor of a tagged type; otherwise we have a dummy
-	conflict between this entity and the aliased entity.
-	(Disambiguate): The predefined equality on universal_access is not
-	usable if there is a user-defined equality with the proper signature,
-	declared in the same declarative part as the designated type.
-	(Find_Unique_Type): The universal_access equality operator defined under
-	AI-230 does not cover pool specific access types.
-	(Covers): If one of the types is a generic actual subtype, check whether
-	it matches the partial view of the other type.
-
-2006-02-13  Thomas Quinot  <quinot@adacore.com>
-
-	* sinput-d.adb (Write_Line): Update the Source_Index_Table after each

-	raise Constraint_Error.
-
-	* s-vallli.adb (Scan_Long_Long_Integer): Call
-	Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we

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

-	nothing since if we are using the non-tasking version it
-	means that the task termination functionality is not used.

-	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.

-	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

-
-	* 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

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

-	Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
-	primary dispatch table for a type.

-
-	* 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

-	(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

-	(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_

-	(Complete_Object_Operation): Retain the entity of the

-	(Analyze_One_Call): Improve location of the error message associated

-	from some abstract ancestor type.
-	(New_Overloaded_Entity): For an overriding entity that comes from

-	(Check_Conformance, Type_Conformant): Addition of one new formal
-	to skip controlling formals in the analysis. This is used to

-	* sem_res.adb (Resolve_Membership_Op): In case of the membership test
-	"Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
-	the expander will generate the corresponding run-time check to evaluate
-	the expression.
-	(Resolve_Call): Check for legal type of procedure name or prefix that
-	appears as a trigger in a triggering alternative.
-	(Valid_Conversion): If expression is ambiguous and the context involves
-	an extension of System, remove System.Address interpretations.
-	(Resolve_Qualified_Expression): Reject the case of a specific-type
-	qualification applied to a class-wide argument. Enhance comment
-	to explain checking of Original_Node.
-	(Resolve_Type_Conversion): The location of the error message was not
-	general enough to handle the general case and hence it has been removed.
-	In addition, this patch improves the text of the message.
-	(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.
-	(Resolve_Allocator): If the context is an unchecked conversion, the
-	allocator inherits its storage pool, if any, from the target type of
-	the conversion.

-	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 in the parent of the concurrent type).

-	(Dispatch_Table): The expander computes the actual array size, allocates

-
-	* sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
-	bounds that may contain functions calls, to prevent memory leaks when
-	the bound contains a call to a function that uses the secondary stack.
-	(Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
-	generate temporaries for loop bounds that might contain function calls
-	that require secondary stack and/or finalization actions.
-
-	* sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
-	selected component and the selector is overloadable (not just a
-	function) treat as function call, Analyze_Call will disambiguate if
-	necessary.
-	(Analyze_Selected_Component): Do not generate an actual subtype for the
-	selected component if expansion is disabled. The actual subtype is only
-	needed for constraint checks.

-	No_Streams no longer prohibits with'ing this package.
-
-	* sem_ch3.adb (Build_Derived_Record_Type): If the parent type has

-	no discriminant constraint to inherit. Such a discrepancy can arise
-	when the actual for a formal type with unknown discriminants is a
-	similar private type whose full view has discriminants.

-
-	* g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
-	(Check_Selector): Use C_Recv instead of C_Read.
-	Selectors are the GNAT.Sockets abstraction to perform a select()

-	* expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
-	"__unix__" instead of "unix".
-	The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
-	sections were just mistakenly ignored. The former is
-	implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
-	Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
-	of hpux. This prevents an unwanted definition of the symbol
-	convert_addresses in adaint.o.

-
-	* decl.c (gnat_to_gnu_field): Use the type of the inner object for a

-	be expandable in place even if the aggregate does not come from source.
-	(Convert_Array_Aggr_In_Allocator): New procedure to initialize the

-
-	* sem_ch12.adb (In_Main_Context): Predicate to determine whether the

-
-	* sem_elab.adb (Check_Elab_Call): Do not check a call that does not

-	    Ed Schonberg   <schonberg@gnat.com>
-
-	* sem_util.adb (Is_Aliased_View): Defend against the case where this
-	subprogram is called with a parameter that is not an object name. This

-	later, and in this case it is wrong to call Is_Aliased, as that might
-	cause a compiler crash.
-	(Explain_Limited_Type): Refine previous fix to include
-	inherited components of derived types, to provide complete information.
-
-	* exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
-	is the prival for a protected object.
-	It is necessary to mark this entity as a variable, in addition to
-	flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
-	modified to avoid checking the Aliased flag on entities that are not
-	objects. (Checking that flag for non-objects is erroneous and could
-	lead to a compiler crash).
-
-2004-10-26  Robert Dewar  <dewar@gnat.com>
-
-	* s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if

-	(Succ): Remove the same redundant test, and also fix the primary test
-	to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.

-	now that we no longer initialize packed modular arrays to zero.
-
-	* exp_dbug.ads: Clarify documentation on handling of PAD and JM

-
-	PR ada/17540
-	* sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,

-
-	* decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
-	dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This

-2004-09-21  Robert Dewar  <dewar@gnat.com>
-
-	* decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular

-	for such types (and in particular ensures that equality testing will
-	only read the relevant bits).
-	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
-	These changes mean that we no longer need to initialize small packed
-	arrays.
-	(gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
-	optimization to an LJM field as to its parent field.
-
-	* ada-tree.h, trans.c, utils.c, utils2.c:

-
-	PR ada/17540
-	* freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public

-	Expand_Record_Extension.
-	(Build_Record_Init_Proc.Build_Assignment): The default expression in

-	It is therefore necessary to take a copy of the expression when building
-	the corresponding assignment statement in the init proc.
-	As a side effect, in the case of a derived record type, we now see the
-	original expression, without any rewriting that could have occurred
-	during expansion of the ancestor type's init proc, and we do not need
-	to go back to Original_Node.

-	subprogram. The proxy object is used as the designated object
-	for RAS values on the same partition (unless All_Calls_Remote applies).
-	(Build_Get_Unique_RP_Call): New subprogram. Build a call to
-	System.Partition_Interface.Get_Unique_Remote_Pointer.
-	(Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):

-	type derived from an actual.
-
-	* exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
-	add a polling call if the subprogram is to be inlined by the back-end,
-	to avoid repeated calls with multiple inlinings.
-

-
-	* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
-	attribute reference does not denote a subtype, it can be any

-	dereference.  In particular, the prefix can be a view conversion for
-	a classwide type (for which Is_Object_Reference holds), but it can
-	also be a value conversion for an access-to-classwide type. In the
-	latter case, there is an implicit dereference, and the original node
-	for the prefix does not verify Is_Object_Reference.
-
-	* sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
-	conversion of a discriminant-dependent component of a mutable object
-	is one itself.

-2004-03-25  Ed Schonberg  <schonberg@gnat.com>

-	instance.
-
-2004-03-25  Gary Dismukes  <dismukes@gnat.com>
-
-	* sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
-	value expressions to ensure that calls within a component definition
-	will be checked (since those are evaluated during the record type's
-	elaboration).

-
-	* sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying

-
-	* sem_ch6.adb (Build_Body_To_Inline): Use an internal name without

-
-	* decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
-	as regular exception objects and not as mere integers representing the
-	condition code.  The latter approach required some dynamics to mask off
-	severity bits, which did not fit well into the GCC table based model.
-	(gnat_to_gnu_entity, objects): Don't supply an external name for VMS
-	exception data objects. We don't it and it would conflict with the other
-	external symbol we have to generate for such exceptions.
-
-	* trans.c (tree_transform, case N_Exception_Handler): Remove part of

-	as regular exceptions objects.

-	accessor instead.
-
-	* cstand.adb (Create_Standard): Adjust the type of the Import_Code
-	component of Standard_Exception_Type to be the closest possible to
-	Exception_Code in System.Standard_Library, that we cannot get at this

-	* bindgen.adb: Configurable_Run_Time mode no longer suppresses the

-	a dummy empty library).
-
-	* targparm.ads: Configurable_Run_Time mode no longer affects linker
-	options (-L parameters and standard libraries). What we plan to do is

-
-	* exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

-	In case of default initialized aggregate with tasks this parameter is
-	used to generate a null string (this is just a workaround that must be
-	improved later). In case of discriminants, this parameter is used to
-	generate a selected component node that gives access to the discriminant
-	value.
-
-	* exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New

-	instead of simple checksum.
-	(CRC_Match): new function.
-	(CRC_Error): new constant.
-
-	* ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
-	a CRC now and not a simple checksum. A CRC uses lower-case hex
-	letters, fixes ambiguity in parsing.
-
-	* ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
-	is what this variable will store.
-
-	* bcheck.adb: Change reference to chechsum in comments by CRC.
-	(Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.

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

-	* s-crc32.adb: Initial version from GNAT.CRC32. This is the version
-	for the compiler.
-
-	* ali-util.adb: Redo previous change to avoid using word CRC everywhere
-	Add 2001 to copyright notice

-	the word Checksum. Add 2001 to copyright notice.

-	* ali.adb: Undo some of previous changes, not needed.
-	Keep the change for lower case letters in the checksum.
-
-	* ali.ads: Undo previous change not needed.

+	(GNATMAKE_RTL_OBJS): add g-crc32.o
+
+	* ali-util.adb:
+	(CRC_Match): new function.
+	(Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
+	instead of the previous simple checksum algorithm.
+	(Time_Stamp_Mismatch): use CRC_Match for comparison.
+	(Set_Source_Table): idem.
+
+	* ali-util.ads:
+	(Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
+	instead of simple checksum.
+	(CRC_Match): new function.
+	(CRC_Error): new constant.
+
+	* ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
+	a CRC now and not a simple checksum. A CRC uses lower-case hex
+	letters, fixes ambiguity in parsing.
+
+	* ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
+	is what this variable will store.
+
+	* bcheck.adb: Change reference to chechsum in comments by CRC.
+	(Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
+	rename All_Checksum_Match to All_CRC_Match. Change due to API
+	renaming since now GNAT does not use a simple checksum but a
+	CRC using GNAT.CRC32.
+
+	* gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
+	now and not anymore a simple checksum.
+
+	* lib-load.adb: Use Source_CRC instead of Source_Checksum in many
+	places.

+	* scans.ads:
+	With GNAT.CRC32.
+	(Checksum): rename to CRC.
+	(Saved_Scan_State): Save_Checksum field renamed to Save_CRC
+
+	* scn-nlit.adb: Rename many Accumulate_Checksum to Update (from

+	* scn-slit.adb: Rename many Accumulate_Checksum to Update (from
+	GNAT.CRC32).  Update copyright notice.
+
+	* scn.adb:
+	(Accumulate_Checksum): removed.

+	Source_CRC in S initialization.
+

+	Update comments for the CRC.
+
+	* types.adb (Hex): Use lowercase for the letter part.
+
+	* types.ads (Get_Hex_String): Returns the hexadecimal representation
+	for a word. This is currently used only for CRC. In previous version,
+	the checksum was using a representation with all letter being
+	upper-case. With the new implementation (using CRC) we do not remove
+	the 32th bit of the CRC, so we can have an upper-case starting letter
+	in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
+	It is ambigous since the CRC was optional and could be followed by
+	options like EB, EE. So now this routines uses lower-case letter for
+	the hexadecimal representation. Strange enough only lower case letters
+	where checked in Scan_ALI (even if this was not a possible case).
+
+	* gnatvsn.ads (Library_Version): changed to 3.15a.
+
+	* s-crc32.ads: Initial version from GNAT.CRC32. This is the version
+	for the compiler.
+
+	* s-crc32.adb: Initial version from GNAT.CRC32. This is the version
+	for the compiler.
+
+	* ali-util.adb: Redo previous change to avoid using word CRC everywhere
+	Add 2001 to copyright notice
+	(Accumulate_Checksum): Modify to use System.CRC32.
+
+	* ali-util.ads: Redo changes of previous revision to continue to use
+	the word Checksum. Add 2001 to copyright notice.
+
+	* ali.adb: Undo some of previous changes, not needed.
+	Keep the change for lower case letters in the checksum.
+
+	* ali.ads: Undo previous change not needed.
+
+	* bcheck.adb: Undo most of previous change, not needed.
+	But do use Checksums_Match for checksum comparison.
+
+	* gnatls.adb: Undo most of previous change, not needed.
+	But do use Checksums_Match for comparing checksums.
+
+	* lib-load.adb: Undo previous change, not needed.
+
+	* lib-writ.adb: Undo previous change, not needed.
+
+	* lib-writ.ads: Document that checksums use lower case,

+
+	* sinput.adb: Undo previous change, not needed.
+
+	* sinput-l.adb: Undo previous change, not needed.
+
+	* sinput.ads: Undo previous change, not needed.  Keep only comment
+	on new checksum algorithm
+
+	* Makefile.in: Add s-crc32 as needed, remove g-crc32.
+	Also remove a-tags and a-stream from GNAT sources.
+
+	* ali.adb (Scan_ALI): fix typo introduce in latest check-in.
+
+	* Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.

+	a dummy empty library).
+
+	* targparm.ads: Configurable_Run_Time mode no longer affects linker
+	options (-L parameters and standard libraries). What we plan to do is

+
+2003-12-08  Javier Miranda  <miranda@gnat.com>
+
+	* exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
+	aggregate in the parent. Otherwise constants with limited aggregates
+	are not supported. Add new formal to pass the component type (Ctype).

+	default initialized components.
+	(Gen_Assign): In case of default-initialized component, generate a
+	call to the IP subprogram associated with the component.
+	(Build_Record_Aggr_Code): Remove the aggregate from the parent in case
+	of aggregate with default initialized components.
+	(Has_Default_Init_Comps): Improve implementation to recursively check
+	all the present expressions.
+
+	* exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
+	to indicate that the initialization call corresponds to a
+	default-initialized component of an aggregate.
+	In case of default initialized aggregate with tasks this parameter is
+	used to generate a null string (this is just a workaround that must be
+	improved later). In case of discriminants, this parameter is used to
+	generate a selected component node that gives access to the discriminant
+	value.
+
+	* exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
+	subprogram, based on Build_Task_Allocate_Block, but adapted to expand
+	allocated aggregates with default-initialized components.
+
+	* par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
+	the box notation is used in positional aggregates.
+
+2003-12-08  Samuel Tardieu  <tardieu@act-europe.fr>

+	(Parse): New Boolean parameter Store_Comments, defaulted to False.
+	Set the scanner to return ends of line and comments as tokens, if
+	Store_Comments is True.
+	(Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
+	comments are associated with these nodes. Store the node IDs in the
+	With_Records.
+	(Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
+	With_Records.
+	(Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
+	the N_Project node. Call Tree.Save and Tree.Reset before scanning the
+	current project. Call Tree.Restore afterwards. Set the various nodes
+	for comment storage (Next_End, End_Of_Line, Previous_Line,
+	Previous_End).
+
+	* prj-part.ads (Parse): New Boolean parameter Store_Comments,
+	defaulted to False.
+
+	* prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
+	to False. When Truncated is True, truncate the string, never go to the
+	next line.
+	(Write_End_Of_Line_Comment): New procedure
+	(Print): Process comments for nodes N_With_Clause,
+	N_Package_Declaration, N_String_Type_Declaration,
+	N_Attribute_Declaration, N_Typed_Variable_Declaration,
+	N_Variable_Declaration, N_Case_Construction, N_Case_Item.
+	Process nodes N_Comment.
+
+	* prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
+	without comments and there are some comments, set the flag
+	Unkept_Comments to True.
+	(Scan): If there are comments, set the flag Unkept_Comments to True and
+	clear the comments.
+	(Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
+	(Next_End_Nodes: New table
+	(Comment_Zones_Of): New function
+	(Scan): New procedure; moved from Prj. Accumulate comments in the
+	Comments table and set end of line comments, comments after, after end
+	and before end.
+	(Add_Comments): New procedure
+	(Save, Restore, Seset_State): New procedures
+	(There_Are_Unkept_Comments): New function
+	(Set_Previous_Line_Node, Set_Previous_End_Node): New procedures
+	(Set_End_Of_Line, Set_Next_End_Node, Remove_Next_End_Node): New
+	procedures.
+	(First_Comment_After, First_Comment_After_End): New functions
+	(First_Comment_Before, First_Comment_Before_End): New functions
+	(Next_Comment): New function
+	(End_Of_Line_Comment, Follows_Empty_Line,
+	Is_Followed_By_Empty_Line): New functions
+	(Set_First_Comment_After, Set_First_Comment_After_End): New procedures
+	(Set_First_Comment_Before, Set_First_Comment_Before_End): New procedures
+	(Set_Next_Comment): New procedure
+	(Default_Project_Node): Associate comment before if the node can store
+	comments.
+
+	* scans.ads (Token_Type): New enumeration value Tok_Comment
+	(Comment_Id): New global variable
+
+	* scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
+	defaulted to False.
+	(Scan): Store position of start of comment. If comments are tokens, set
+	Comment_Id and set Token to Tok_Comment when scanning a comment.
+	(Set_Comment_As_Token): New procedure
+
+	* sinput-p.adb: Update Copyright notice
+	(Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
+	that no longer exists.
+
+2003-12-08  Javier Miranda  <miranda@gnat.com>
+
+	* sem_aggr.adb: Add dependence on Exp_Tss package
+	Correct typo in comment
+	(Resolve_Aggregate): In case of array aggregates set the estimated
+	type of the aggregate before calling resolve. This is needed to know
+	the name of the corresponding IP in case of limited array aggregates.
+	(Resolve_Array_Aggregate): Delay the resolution to the expansion phase
+	in case of default initialized array components.
+
+	* sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
+	types. Required to give support to limited aggregates in generic
+	formals.
+
+2003-12-08  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_ch3.adb (Check_Initialization): For legality purposes, an
+	inlined body functions like an instantiation.
+	(Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
+	until bounds are analyzed, to diagnose premature use of type.
+
+	* sem_util.adb (Wrong_Type): Improve error message when the type of
+	the expression is used prematurely.
+
+2003-12-08  GNAT Script  <nobody@gnat.com>
+
+	* Make-lang.in: Makefile automatically updated
+
+2003-12-08  Arnaud Charlet  <charlet@act-europe.fr>
+
+	* sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
+	they are automatically generated by Make-lang.in and cause nothing but
+	maintenance troubles.
+
+2003-12-05  Thomas Quinot  <quinot@act-europe.fr>
+
+	* 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,
+	version of this unit).
+
+2003-12-05  Olivier Hainque  <hainque@act-europe.fr>
+
+	* 53osinte.ads, 54osinte.ads, 55osinte.ads, 56osinte.ads, 5bosinte.ads,
+	5cosinte.ads, 5hosinte.ads, 5iosinte.ads, 5losinte.ads,
+	5tosinte.ads: Define the SA_SIGINFO constant, to allow references from
+	the body of System.Interrupt_Management common to several targets.
+	Update copyright notice when appropriate.
+
+	* 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
+	constant.
+
+	* 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,

+
+2004-12-07  Gary Dismukes  <dismukes@adacore.com>

+	procedure Protected_Single_Entry_Call.
+	(Lock_Read_Only_Entry): Remove the code for raising Program_Error for
+	Detect_Blocking which is redundant with the check done within the
+	procedure Protected_Single_Entry_Call.
+
+2004-11-18  Vincent Celier  <celier@adacore.com>
+
+	* makegpr.adb (Compile): Put the compiling switches (in package
+	Compiler and on the command line) immediately after "-c", instead of
+	at the end of the command line invocation of the compiler, when
+	compiling a non-Ada file.
+	(Build_Global_Archive): When there is no need to rebuild the archive,
+	set Global_Archive_Exists, so that the archive is passed to the linker
+	if one is needed.

+	Remove extra paren check from list of checks for redundant constructs
+	Add documentation of new -gnatyx style check (check extra parens)
+	Remove paragraph about gnatelim debug options.
+
+	* gnat_rm.texi: Document that Ada.Streams now forbids creating stream
+	objects rather than forbidding dependencies on the package Ada.Streams.
+
+	* sinfo.ads: Add ??? note that we should document pragmas passed to
+	back end.
+

+
+	* g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
+	(C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
+	there is no use of GNAT.Sockets.Constants.
+	Remove remaining pragma Import for C_Write
+	Remove C_Read and C_Write from internal implementation unit
+	GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
+	the read and write functions from the system runtime library is fine
+	on UNIX but won't work under Windows).
+
+	* g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
+	(Check_Selector): Use C_Recv instead of C_Read.
+	Selectors are the GNAT.Sockets abstraction to perform a select()
+	call on a set of descriptors. To allow abortion of an ongoing
+	select operation, some data is written to a dedicated socket that
+	is always monitored.
+	Under Windows, the write and read library functions cannot operate
+	on sockets, so we need to use send and recv instead, which is portable
+	across all supported platforms.
+
+	* g-socthi.ads: Remove C_Read and C_Write from internal implementation
+	unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
+	(using the read and write functions from the system runtime library is
+	fine on UNIX but won't work under Windows).

+
+	* Makefile.in: Add support for building shared libraries under Darwin.
+	(EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
+	the low level EH init subprogram to be called from __gnat_initialize.
+
+	* mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
+	indicates which options to pass to the archive indexer.
+
+	* mlib-utl.adb: Add support for calling ranlib with additional
+	options. This is needed for instance under Mac OS X.
+	(Ranlib_Options): New global variable, used to store the potential
+	options to pass to ranlib.
+	(Ar): Use Ranlib_Options when spawning ranlib.
+	(Initialize): Set the value of ranlib option.
+
+2004-10-26  Olivier Hainque  <hainque@act-europe.fr>
+
+	* s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K

+	in the ZCX case.
+
+2004-10-26  Pascal Obry  <obry@gnat.com>
+
+	* s-parame-mingw.adb (Default_Stack_Size): Add some comments.
+
+	* s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
+	Windows only the initial thread stack size can be set so it is good to
+	start we a low stack size.
+	The OS will adjust the size as needed.
+
+2004-10-26  Olivier Hainque  <hainque@act-europe.fr>
+	    Nicolas Setton  <setton@act-europe.fr>
+
+	* expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
+	"__unix__" instead of "unix".
+	The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
+	sections were just mistakenly ignored. The former is
+	implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
+	Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
+	of hpux. This prevents an unwanted definition of the symbol
+	convert_addresses in adaint.o.
+
+2004-10-26  Gary Dismukes  <dismukes@gnat.com>
+
+	* a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for

+	expression is the right-hand side of an assignment.
+
+2004-10-26  Vincent Celier  <celier@gnat.com>
+
+	* clean.adb (Delete): Do not output warnings when in quiet output and
+	not in verbose mode.
+	(Force_Deletions): New Boolean flag, defaulted to False
+	(Delete): Only delete a file if it is writable, and when
+	Force_Deletions is True.
+	(Parse_Cmd_Line): New switch -f: set Force_Deletions to True
+	(Usage): Line for new switch -f
+	(Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
+	own.
+
+2004-10-26  Eric Botcazou  <ebotcazou@act-europe.fr>
+
+	* decl.c (gnat_to_gnu_field): Use the type of the inner object for a
+	JM type only if its size matches that of the wrapper.  When a size is
+	prescribed and the field is not aliased, remove the wrapper of a JM
+	type only if the size is not greater than that of the packed array.
+	(gnat_to_gnu_entity): Change the extension of packed array wrappers

+	(Pred): Implement in terms of Succ.
+
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+
+	* exp_aggr.adb (Safe_Component): An aggregate component that is an
+	unchecked conversion is safe for in-place use if the expression of the
+	conversion is safe.
+	(Expand_Array_Aggregate): An aggregate that initializes an allocator may
+	be expandable in place even if the aggregate does not come from source.
+	(Convert_Array_Aggr_In_Allocator): New procedure to initialize the
+	designated object of an allocator in place, rather than building it
+	first on the stack. The previous scheme forces a full copy of the array,
+	and may be altogether unsusable if the size of the array is too large
+	for stack allocation.
+
+2004-10-26  Robert Dewar  <dewar@gnat.com>
+
+	* exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array

+	is aliased and is a by_reference type, do not pass by copy.
+	(Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
+	detect whether the call is in the right side of an assignment or
+	the expression of an object declaration.  Recurse on component
+	association within aggregates.
+	Call it in the condition that determines whether the temporary is
+	necessary for correct stack-checking.
+
+2004-10-26  Thomas Quinot  <quinot@act-europe.fr>
+
+	* exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
+	RACW_Type, used in the PolyORB version.
+	Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
+	version and the GARLIC version.
+
+	* snames.ads, snames.adb, s-parint.ads, s-parint.adb:
+	Rename RCI_Info to RCI_Locator for better consistency between the
+	GARLIC and PolyORB versions of the distributed systems annex.
+	(DSA_Implementation_Name): This enumeration lists the possible
+	implementations of the Partition Communication Subsystem for the
+	Distributed Systems Annex (DSA). The three available implementations
+	are the dummy stub implementation (No_DSA), and two versions based on
+	two different distribution runtime libraries: GARLIC and PolyORB. Both
+	the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
+	technology.
+	Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
+	that organization.
+
+	* rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
+	between the GARLIC and PolyORB versions of the distributed systems
+	annex.
+	Remove RE_Unbounded_Reclaim_Pool since it is unused.
+
+2004-10-26  Gary Dismukes  <dismukes@gnat.com>

+
+	* g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,

+	These new routines allow the user to set or unset the Owner execute
+	and Owner write permission flags on a file.
+
+	* makegpr.adb, mlib.adb, mlib-prj.adb: Use
+	GNAT.OS_Lib.Set_Executable instead of rolling our own.
+
+2004-10-26  Matthew Gingell  <gingell@gnat.com>
+
+	* i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
+
+2004-10-26  Pascal Obry  <obry@gnat.com>
+
+	* init.c (__gnat_error_handler) [Win32]: Instead of trying to read the

+	access for this address using appropriate Win32 routine.
+	(HPUX sections): guard with "__hpux__" instead of "hpux".
+
+2004-10-26  Robert Dewar  <dewar@gnat.com>
+
+	* lib-xref.adb (Generate_Reference): Don't complain about reference to

+
+	* prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual

+	(Parse): For an extending all project, allow direct import of a project
+	that is virtually extended.
+
+	* prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
+	the specified name is directly imported, return its ID. Otherwise, if

+	    Javier Miranda  <miranda@gnat.com>
+
+	* sem_ch12.adb (In_Main_Context): Predicate to determine whether the
+	current instance appears within a unit that is directly in the context
+	of the main unit.
+	Used to determine whether the body of the instance should be analyzed
+	immediately after its spec, to make its subprogram bodies available
+	for front-end inlining.
+	(Analyze_Formal_Array_Type): Cleanup condition that checks that range

+
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
+	or protected type with discriminants, do not constrain the
+	corresponding record type if the subtype declaration has no
+	discriminant constraints. This can be the case in source code, or in
+	the subtype declaration created to rename an actual type within an
+	instantiation.
+
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
+	different kind of stub (possibly wrong name for file), do not check
+	for conformance.
+	(Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
+	includes call to some function that returns an unconstrained type, do
+	not inline.
+
+2004-10-26  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_elab.adb (Check_Elab_Call): Do not check a call that does not
+	appear in the code for the main unit. Dependencies among units in the
+	context of the main unit are established when those other units are
+	compiled. Otherwise spurious elaboration constraints can generate

+2004-10-26  Thomas Quinot  <quinot@act-europe.fr>
+	    Ed Schonberg   <schonberg@gnat.com>
+
+	* sem_util.adb (Is_Aliased_View): Defend against the case where this
+	subprogram is called with a parameter that is not an object name. This
+	situation arises for some cases of illegal code, which is diagnosed
+	later, and in this case it is wrong to call Is_Aliased, as that might
+	cause a compiler crash.
+	(Explain_Limited_Type): Refine previous fix to include
+	inherited components of derived types, to provide complete information.
+
+	* exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
+	is the prival for a protected object.
+	It is necessary to mark this entity as a variable, in addition to
+	flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
+	modified to avoid checking the Aliased flag on entities that are not
+	objects. (Checking that flag for non-objects is erroneous and could
+	lead to a compiler crash).
+
+2004-10-26  Robert Dewar  <dewar@gnat.com>
+
+	* s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
+	X_Frac = 0.5, then we know that the number X must be positive.
+	(Succ): Remove the same redundant test, and also fix the primary test
+	to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
+	Minor reformatting
+	(Decompose): Add fuller comments to spec
+
+2004-10-26  Pascal Obry  <obry@gnat.com>
+
+	* tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr

+	(VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
+	segmentation violation.
+
+2004-10-26  Eric Botcazou  <ebotcazou@act-europe.fr>
+
+	* trans.c (call_to_gnu): For an (in-)out parameter passed by reference

+	memory pools provided as part of the GNAT library.
+	Remove "virtual" from declaration of A::method2 in
+	the simple example of Ada/C++ mixed system.
+	Library Projects may be virtually extended: their virtual extensions

+	with the kernel.
+
+2004-10-04  Javier Miranda  <miranda@gnat.com>

+
+2004-10-04  Robert Dewar  <dewar@gnat.com>
+
+	* exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no

+
+	* checks.adb (Expr_Known_Valid): Packed arrays are now always
+	considered valid, even if the representation is modular. That's correct
+	now that we no longer initialize packed modular arrays to zero.
+
+	* exp_dbug.ads: Clarify documentation on handling of PAD and JM
+	suffixes. These are now documented as the only cases in which the
+	debugger ignores outer records.
+	Previously, the spec allowed arbitrary suffixes for this purpose.
+	Change name of LJM to JM for packed array pad records
+	Create separate section on packed array handling, and add a whole new

+2004-10-04  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
+	Inline_Always when in Configurable_Run_Time mode.
+
+	* sem_prag.adb (Process_Convention): If entity is an inherited
+	subprogram, apply convention to parent subprogram if in same scope.
+	(Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
+	when in Configurable_Run_Time mode.
+
+2004-10-04  Ed Schonberg  <schonberg@gnat.com>

+
+2004-10-04  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_ch12.adb (Check_Generic_Actuals): New predicate
+	Denotes_Previous_Actual, to handle properly the case of a private
+	actual that is also the component type of a subsequent array actual.
+	The visibility status of the first actual is not affected when the
+	second is installed.
+	(Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
+	make fully recursive the treatment of formals of packages declared
+	with a box.
+	(Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
+	the above on exit from an instantiation.
+	(Denotes_Formal_Package): When called from Restore_Private_Views, ignore
+	current instantiation which is now complete.
+	(Analyze_Package_Instantiation): No instantiated body is needed if the
+	main unit is generic. Efficient, and avoid anomalies when a instance
+	appears in a package accessed through rtsfind.
+
+2004-10-04  Ed Schonberg  <schonberg@gnat.com>
+
+	* exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
+	do not generate a declaration for a temporary if the call is part of a
+	library-level instantiation.
+
+2004-10-04  Ed Schonberg  <schonberg@gnat.com>
+
+	* sem_util.adb (Explain_Limited_Type): Ignore internal components when
+	searching for a limited component to flag.
+
+	* exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
+	expansion of Input, to account for the fact that the implicit call
+	generated by the attribute reference must freeze the user-defined
+	stream subprogram. This is only relevant to 'Input, because it can
+	appear in an object declaration, prior to the body of the subprogram.
+
+	* sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
+	expansion can proceed and further errors uncovered.
+	(Minor clean up): Fix cases of using | instead of \ for continuation
+	messages.

+	(Gprmake): Do not allow mains on the command line for library projects.
+	Do not attempt to link when the project is a library project.
+	(Library_Opts): New table to store Library_Options.

+
+	* s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
+	Stack_Address argument.
+	Check that its value is equal to Null_Address because this target does

+
+2004-10-04  Thomas Quinot  <quinot@act-europe.fr>
+
+	* usage.adb: Change "pragma inline" to "pragma Inline" in information

+
+2004-10-04  Thomas Quinot  <quinot@act-europe.fr>
+
+	* exp_dist.adb: Split declaration of asynchronous flag out of
+	Add_RACW_Read_Attribute.
+	Minor reformatting for better alignment with PolyORB version.
+	Store the entity for the asynchronous flag of an RACW, rather than the
+	expression, in the asynchronous flags table. This will allow this flag
+	to be used in other subprograms beside Add_RACW_Read_Attribute.
+
+2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

+	g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads:  Add new
+	sockets constant MSG_NOSIGNAL (Linux-specific).
+	Add new sockets constant MSG_Forced_Flags, list of flags to be set on

+	For Linux, set MSG_NOSIGNAL on all send operations to prevent them
+	from trigerring SIGPIPE.
+	Rename components to avoid clash with Ada 2005 possible reserved

+	condition, propagate Socket_Error to the caller.
+
+2004-10-01  Jan Hubicka  <jh@suse.cz>

+
+2004-09-23  Robert Dewar  <dewar@gnat.com>
+
+	PR ada/17540
+	* sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
+	instead do this at freeze time (we won't do it if there is an address
+	clause).
+	Change "pragma inline" to "pragma Inline" in information and error
+	messages.
+	Minor reformatting.
+
+	* freeze.adb (Check_Address_Clause): Remove previous change, not the
+	right way of doing things after all.
+	(Freeze_Entity): For object, set Is_Public for imported entities
+	unless there is an address clause present.
+
+2004-09-21  Olivier Hainque  <hainque@act-europe.fr>
+
+	* decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a

+	their TYPE_SIZE set already.
+
+2004-09-21  Robert Dewar  <dewar@gnat.com>
+
+	* decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
+	packed array types in both little- and big-endian cases. This change
+	ensures that we no longer count on the unused bits being initialized
+	for such types (and in particular ensures that equality testing will
+	only read the relevant bits).
+	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
+	These changes mean that we no longer need to initialize small packed
+	arrays.
+	(gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
+	optimization to an LJM field as to its parent field.
+
+	* ada-tree.h, trans.c, utils.c, utils2.c:
+	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
+
+2004-09-20  Jan Hubicka  <jh@suse.cz>

+
+2004-09-20  Robert Dewar  <dewar@gnat.com>
+

+	Convert the result to File_Size.
+
+	* prj.ads: (Project_Error): New exception
+
+	* prj-attr.adb: Except in procedure Initialize, Fail comes from

+	(Attrs, Package_Attributes): Tables moved to private part of spec
+	(Add_Attribute, Add_Unknown_Package): Moved to new child package
+	Prj.Attr.PM.
+	(Register_New_Package (Name, Attributes), Register_New_Attribute): Raise

+	(Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
+	Fail. Check that package name is not already in use.
+
+	* prj-attr.ads: Comment updates to indicate that all subprograms may be
+	used by tools, not only by the project manager, and to indicate that

+
+	* init.c: Add the global variable __gl_detect_blocking that indicates
+	whether pragma Detect_Blocking is active (1) or not (0). Needed for

+	(__gnat_set_globals): Pass and update the detect_blocking parameter.
+
+	* lib-writ.adb (Write_ALI): Set the DB flag in the ali file if

+
+	* lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
+
+	* ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
+	DB is found in the ali file. Any unit compiled with pragma
+	Detect_Blocking active forces its effect in the whole partition.
+
+	* a-retide.adb (Delay_Until): Raise Program_Error if pragma
+	Detect_Blocking is active and delay is called from a protected

+	package.
+
+	* s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.

+
+	* sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
+	subprogram.
+	New implementation of expansion for remote access-to-subprogram types,
+	based on the RACW infrastructure.
+	This version of sem_dist is compatible with PolyORB/DSA as well as
+	GLADE.
+
+	* sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
+	Asynchrronous that applies to a remote access-to-subprogram type, mark
+	the underlying RACW type as asynchronous.
+
+	* link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and

+
+	* Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
+	g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

+
+	* atree.adb: Minor reformatting
+
+	* exp_ch3.adb (Expand_Derived_Record): Rename to
+	Expand_Record_Extension.
+	(Build_Record_Init_Proc.Build_Assignment): The default expression in
+	a component declaration must remain attached at that point in the
+	tree so New_Copy_Tree copies it if the enclosing record type is derived.
+	It is therefore necessary to take a copy of the expression when building
+	the corresponding assignment statement in the init proc.
+	As a side effect, in the case of a derived record type, we now see the
+	original expression, without any rewriting that could have occurred
+	during expansion of the ancestor type's init proc, and we do not need
+	to go back to Original_Node.
+
+	* exp_ch3.ads (Expand_Derived_Record): Rename to
+	Expand_Record_Extension.

+	New subprograms. Used to create a proxy tagged object for a remote
+	subprogram. The proxy object is used as the designated object
+	for RAS values on the same partition (unless All_Calls_Remote applies).
+	(Build_Get_Unique_RP_Call): New subprogram. Build a call to
+	System.Partition_Interface.Get_Unique_Remote_Pointer.
+	(Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):

+
+	* exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
+	add a polling call if the subprogram is to be inlined by the back-end,
+	to avoid repeated calls with multiple inlinings.
+
+	* checks.adb (Apply_Alignment_Check): If the expression in the address

+
+	* a-numaux-x86.adb (Reduce): Reimplement using an approximation of Pi

+
+	* exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in

+	leave it more clear.
+	(Analyze_Type_Declaration): If type has previous incomplete tagged
+	partial view, inherit properly its primitive operations.

+	interfaces.
+	(Analyze_Interface_Declaration): New procedure for use for regular and
+	formal interface declarations.
+	(Build_Derived_Record_Type): Add support for private types to the code

+	(Access_Type_Declaration): Clean up declaration of malformed type
+	declared as an access to its own classwide type, to prevent cascaded
+	crash.
+	(Collect_Interfaces): For private extensions and for derived task types
+	and derived protected types, the parent may be an interface that must
+	be included in the interface list.
+	(Access_Definition): If the designated type is an interface that may
+	contain tasks, create Master_Id for it before analyzing the expression

+	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

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

+
+	* sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to

+	(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

+	With_Clause
+	(Install_Limited_With_Clause): Introduce implicit limited_with_clause

+	(Expand_Limited_With_Clause): Even if the unit in the implicit

+
+	* 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

+	(Access_Subprogram_Declaration): Handle creation of the type entity for

+	(Analyze_Subtype_Declaration): Modify the text of error message.

+	(Build_Derived_Record_Type): Code cleanup to avoid calling

+	subprogram Complete_Subprograms_Derivation already does the
+	job associated with the second call.
+

+	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

+
+	* sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous

+	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

+	(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.
+	(Base_Types_Match): Add missing case for types imported from
+	limited-with clauses
+	(New_Overloaded_Entity): Add barrier to protect the use of

+	    Ed Schonberg  <schonberg@adacore.com>
+
+	* sem_disp.adb (Check_Controlling_Formals): Anonymous access types
+	used in controlling parameters exclude null because it is necessary to

+
+	* sem_res.adb (Resolve_Membership_Op): In case of the membership test
+	"Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
+	the expander will generate the corresponding run-time check to evaluate
+	the expression.
+	(Resolve_Call): Check for legal type of procedure name or prefix that
+	appears as a trigger in a triggering alternative.
+	(Valid_Conversion): If expression is ambiguous and the context involves
+	an extension of System, remove System.Address interpretations.
+	(Resolve_Qualified_Expression): Reject the case of a specific-type
+	qualification applied to a class-wide argument. Enhance comment
+	to explain checking of Original_Node.
+	(Resolve_Type_Conversion): The location of the error message was not
+	general enough to handle the general case and hence it has been removed.
+	In addition, this patch improves the text of the message.
+	(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.
+	(Resolve_Allocator): If the context is an unchecked conversion, the

+	(Interface_Present_In_Ancestor): In case of concurrent types we can't
+	use the Corresponding_Record_Typ attribute to look for the interface

+	describing the new layout.
+	(Dispatch_Table): The expander computes the actual array size, allocates
+	the Dispatch_Table record accordingly, and generates code that displaces

+	subprogram only if inner one comes from source.
+	(Analyze_Function_Call): If the call is given in object notation, the

+	(Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
+	mark in function specification, in a context where the formals are
+	visible and hide outer homographs.
+
+	* sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
+	as the tagged type for the cases of abstract formal subprograms and
+	renamings of those.  Clean up spec comments.

+	procedure", covering the case of a call to a formal abstract procedure
+	that has statically tagged operands.
+	(Check_Dispatching_Call): Check for the case of an actual given by
+	a tag-indeterminate function call whose type is an ancestor of the
+	containing call's associated tagged type. This situation can occur
+	for inherited primitives with function defaults. In this case we
+	use the tagged type's tag directly as the controlling argument for
+	the calls.
+	(Expand_Call): Name change on call to Expand_Dispatch_Call.
+

+	(Valid_Conversion): For a conversion to a numeric type occurring in an

+	if its type is an aggregate.

+	discriminant is used to constrain a private component of the type, and
+	expansion is disabled.
+	(Find_Type_Of_Object): Do not treat a return subtype that is an
+	anonymous subtype as a local_anonymous_type, because its accessibility
+	level is the return type of the enclosing function.
+	(Check_Initialization): In -gnatg mode, turn the error "cannot
+	initialize entities of limited type" into a warning.
+	(OK_For_Limited_Init): Return true for generated nodes, since it
+	sometimes violates the legality rules.
+	(Make_Incomplete_Declaration): If the type for which an incomplete

+	now centralized in Generate_Reference.
+	(Install_Limited_Context_Clauses): Remove superfluous error
+	message associated with unlimited view visible through use
+	and renamings. In addition, at the point in which the error

+	Use new // insertion for some continuation messages
+	(Expand_Limited_With_Clause): Use copy of name rather than name itself,
+	to create implicit with_clause for parent unit mentioned in original
+	limited_with_clause.

+	(Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
+	whether the designated type is discriminated with a constrained partial

+	Add local variable Des_Btyp. The Designated_Type

+	access definition.
+	(Instantiate object): Alphabetize local variables. Handle the creation
+	of new renaming declarations with respect to the kind of definition
+	used - either an access definition or a subtype mark. Guard against

+	they have been resolved. Add check for required null exclusion in a
+	formal object declaration.
+	(Switch_View): A private subtype of a non-private type needs to be
+	switched (the base type can have been switched without its private
+	dependents because of the last branch of Check_Private_View.
+	(Check_Private_View): Do not recompute Base_Type (T), instead use cached
+	value from BT.
+	(Instantiate_Type): Emit an error message whenever a class-wide type of
+	a tagged incomplete type is used as a generic actual.
+	(Find_Actual_Type): Extend routine to handle a component type in a child

+	(Try_Object_Operation): If no candidate interpretation succeeds, but

+	error in call rather than on a malformed selected component.
+	(Analyze_Selected_Component): If the prefix is an incomplete type from
+	a limited view, and the full view is available, use the full view to
+	determine whether this is a prefixed call to a primitive operation.
+	(Operator_Check): Verify that a candidate interpretation is a binary
+	operation before checking the type of its second formal.
+	(Analyze_Call): Add additional warnings for function call contexts not
+	yet supported.
+	(Analyze_Allocator): Move the check for "initialization not allowed for
+	limited types" after analyzing the expression. This is necessary,
+	because OK_For_Limited_Init looks at the structure of the expression.
+	Before analysis, we don't necessarily know what sort of expression it
+	is. For example, we don't know whether F(X) is a function call or an
+	indexed component; the former is legal in Ada 2005; the latter is not.
+	(Analyze_Allocator): Correct code for AI-287 -- extension aggregates
+	were missing. We also didn't handle qualified expressions. Now also
+	allow function calls. Use new common routine OK_For_Limited_Init.
+	(Analyze_Type_Conversion): Do not perform some legality checks in an
+	instance, because the error message will be redundant or spurious.
+	(Analyze_Overloaded_Selected_Component): Do not do style check when
+	setting an entity, since we do not know it is the right entity yet.
+	(Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
+	(Analyze_Overloaded_Selected_Component): Same change
+	(Analyze_Selected_Component): Remove unnecessary prefix type retrieval
+	since regular incomplete subtypes are transformed into corresponding
+	subtypes of their full views.
+	(Complete_Object_Operation): Treat name of transformed subprogram call
+	as coming from source, for browsing purposes.
+	(Try_Primitive_Operation): If formal is an access parameter, compare

+	(Operator_Check): If no interpretation of the operator matches, check

+	(Analyze_A_Return_Statement): Correct casing in error message.
+	Move Pop_Scope to after Analyze_Function_Return, because an extended

+	doesn't work right. Correct use of "\" for continuation messages.
+	(Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than

+	(Resolve_Actuals): If the actual is an allocator whose directly
+	designated type is a class-wide interface we build an anonymous

+	(Make_DT, Make_Secondary_DT): If the tagged type has no user defined
+	primitives we reserve one dummy entry to ensure that the tag does not
+	point to some memory that is associated with some other object. In
+	addition, remove all the old code that generated the assignments
+	associated with the signature of the dispatch table and replace them

+	call to the Input attribute (even when rewritten).
+	(Propagate_Tag): Augment comment to indicate the possibility of a call

+	has Error_Posted set. Prevent infinite loops in illegal programs.
+	(Check_Private_Child_Unit): Move test for a nonprivate with clause down
+	to the point of the error test requiring the current unit to be private.
+	This ensures that private with clauses are not exempted from the basic
+	checking for being a descendant of the same library unit parent as a
+	withed private descendant unit.
+	(Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
+	handle private with clauses properly, as well as to account for cases
+	where the withed unit is a public descendant of a private ancestor
+	(in which case the current unit must be a descendant of the private
+	ancestor's parent). The spec comments were updated accordingly. Also,

+	messages that mirror the errors tested and reported by
+	Check_Private_Child_Unit.
+	Parameter and variable names improved for readability.
+	(Install_Limited_Context_Clauses): Remove test for a withed unit being
+	private as the precondition for calling

+	were not always properly handled previously.
+	(Formal_Entity): Complete rewrite, to handle properly some complex case
+	with multiple levels of parametrization by formal packages.

+	to the corresponding derived type declaration for proper semantics.
+
+	* sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
+	(Check_Component): Enforce restriction on components of
+	unchecked_unions: a component in a variant cannot contain tasks or
+	controlled types.
+	(Unchecked_Union): Allow nested variants and multiple discriminants, to
+	conform to AI-216.
+	Add pragma Ada_2005 (synonym for Ada_05)
+	Properly handle Ada_Version_Explicit and Ada_Version_Config, which

+	Document that pragma Propagate_Exceptions has no effect
+	(Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
+	(Set_Convention_From_Pragma): Check that if a convention is
+	specified for a dispatching operation, then it must be
+	consistent with the existing convention for the operation.
+	(CPP_Class): Because of the C++ ABI compatibility, the programmer is no
+	longer required to specify an vtable-ptr component in the record. For
+	compatibility reasons we leave the support for the previous definition.

+
+	* sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
+	non-overrideen inherited operation with a controlling result as
+	illegal only its implicit declaration comes from the derived type
+	declaration of its result's type.
+	(Check_Possible_Deferred_Completion): Relocate the object definition
+	node of the subtype indication of a deferred constant completion rather
+	than directly analyzing it. The analysis of the generated subtype will
+	correctly decorate the GNAT tree.
+	(Record_Type_Declaration): Check whether this is a declaration for a
+	limited derived record before analyzing components.
+	(Analyze_Component_Declaration): Diagnose record types  not explicitly
+	declared limited when a component has a limited type.
+	(Build_Derived_Record_Type): Code reorganization to check if some of
+	the inherited subprograms of a tagged type cover interface primitives.
+	This check was missing in case of a full-type associated with a private
+	type declaration.
+	(Constant_Redeclaration): Check that the subtypes of the partial and the
+	full view of a constrained deferred constant statically match.
+	(Mentions_T): A reference to the current type in an anonymous access
+	component declaration  must be an entity name.
+	(Make_Incomplete_Type_Declaration): If type is tagged, set type of
+	class_wide type to refer to full type, not to the incomplete one.
+	(Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
+	available. Required to give support to the certified run-time.
+	(Analyze_Component_Declaration): In case of anonymous access components
+	perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
+	(Process_Discriminants): For an access discriminant, use the
+	discriminant specification as the associated_node_for_itype, to
+	simplify accessibility checks.

+	    Javier Miranda  <miranda@adacore.com>
+
+	* sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
+	abstract interpretations on an operator, remove interpretations that
+	yield Address or a type derived from it, if one of the operands is an
+	integer literal.
+	(Try_Object_Operation.Try_Primitive_Operation,
+	Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
+	location when creating the new reference to a primitive or class-wide
+	operation as a part of rewriting a subprogram call.
+	(Try_Primitive_Operations): If context requires a function, collect all
+	interpretations after the first match, because there may be primitive
+	operations of the same type with the same profile and different return
+	types. From code reading.
+	(Try_Primitive_Operation): Use the node kind to choose the proper
+	operation when a function and a procedure have the same parameter
+	profile.
+	(Complete_Object_Operation): If formal is an access parameter and prefix
+	is an object, rewrite as an Access reference, to match signature of
+	primitive operation.
+	(Find_Equality_Type, Find_One_Interp): Handle properly equality given
+	by an expanded name with prefix Standard, when the operands are of an
+	anonymous access type.
+	(Remove_Abstract_Operations): If the operation is abstract because it is
+	inherited by a user-defined type derived from Address, remove it as
+	well from the set of candidate interpretations of an overloaded node.
+	(Analyze_Membership_Op): Membership test not applicable to cpp-class
+	types.
+
+2006-02-13  Bob Duff  <duff@adacore.com>
+
+	* sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
+	redundant use clauses.
+	In particular, if the scope of two use clauses overlaps, but one is not
+	entirely included in the other, we should not warn.  This can happen
+	with nested packages.
+	(Analyze_Subprogram_Renaming): Protect the compiler against previously
+	reported errors. The bug was reported when the compiler was built
+	with assertions enabled.
+	(Find_Type): If the node is a 'Class reference and the prefix is a
+	synchronized type without a corresponding record, return the type
+	itself.
+
+2006-02-13  Javier Miranda  <miranda@adacore.com>
+
+	* sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
+	if this is the full-declaration associated with a private declaration
+	that implement interfaces, then the private type declaration must be
+	limited.
+	(Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
+	as aliased. The use of the 'access attribute is not available for such
+	object (for this purpose the object should be explicitly marked as
+	aliased, but being an anonymous type this is not possible).
+
+2006-02-13  Ed Schonberg  <schonberg@adacore.com>
+	    Robert Dewar  <dewar@adacore.com>
+
+	* sem_elab.adb (Same_Elaboration_Scope): A package that is a

+	    Javier Miranda  <miranda@adacore.com>
+
+	* sem_type.adb (Write_Overloads): Improve display of candidate
+	interpretations.
+	(Add_One_Interp): Do not add to the list of interpretations aliased
+	entities corresponding with an abstract interface type that is an
+	immediate ancestor of a tagged type; otherwise we have a dummy
+	conflict between this entity and the aliased entity.
+	(Disambiguate): The predefined equality on universal_access is not
+	usable if there is a user-defined equality with the proper signature,
+	declared in the same declarative part as the designated type.
+	(Find_Unique_Type): The universal_access equality operator defined under
+	AI-230 does not cover pool specific access types.
+	(Covers): If one of the types is a generic actual subtype, check whether
+	it matches the partial view of the other type.
+
+2006-02-13  Thomas Quinot  <quinot@adacore.com>
+
+	* sinput-d.adb (Write_Line): Update the Source_Index_Table after each
+	line. This is necessary to allow In_Extended_Main_Unit to provide
+	correct results for itypes while writing out expanded source.
+	(Close_File): No need to update the source_index_table here since it's
+	now done for each line.
+
+2006-02-13  Ed Schonberg  <schonberg@adacore.com>
+	    Robert Dewar  <dewar@adacore.com>
+
+	* sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
+	preserve the source unit where the itype is declared, and prevent a
+	backend abort.
+	(Note_Implicit_Run_Time_Call): New procedure
+	(Write_Itype): Handle missing cases (E_Class_Wide_Type and
+	E_Subprogram_Type)
+
+	* sprint.ads: Document use of $ for implicit run time routine call
+
+2006-02-13  Quentin Ochem  <ochem@adacore.com>

+	* s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
+	task name.
+
+2006-02-13  Bob Duff  <duff@adacore.com>
+
+	* s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
+	Scan_Unsigned, so we do not scan leading blanks and sign twice.
+	Integer'Value("- 5") and Integer'Value("-+5") now correctly
+	raise Constraint_Error.
+
+	* s-vallli.adb (Scan_Long_Long_Integer): Call
+	Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
+	do not scan leading blanks and sign twice.
+	Integer'Value("- 5") and Integer'Value("-+5") now correctly
+	raise Constraint_Error.
+
+	* s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
+	Scan_Long_Long_Unsigned): Split out most of the processing from
+	Scan_Long_Long_Unsigned out into
+	Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
+	This prevents scanning leading blanks and sign twice.
+	Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
+	See RM-3.5(44).
+
+	* s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
+	out most of the processing from Scan_Unsigned out into

+	(Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the

+	(*): All subprograms now have an extra parameter with default value to
+	specify which parser should be used. For backward compatibility, it
+	defaults to parsing the command line of the application. They were also
+	modified to properly handle cases where each of the argument does not
+	start at index 1 (which is always true for Ada.Command_Line, but not
+	when processing any Argument_List).
+	(Free): New subprogram
+	(Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
+	Argument): New subprograms
+	(Switch_Parameter_Type): New enum, which clarifies the code. The extra
+	special characters like ':', '=',... are now handled in a single place,
+	which makes the code more extensible eventually.
+	(Getopt, Full_Switch): When the switch was returned as part of the
+	special character '*', make sure it is prepended by the switch character
+	('-' in general), so that the application knows whether "foo" or "-foo"
+	was specified on the command line.

+	(Expand_Subtype_From_Expr): For limited objects initialized with build

+	belong to a private generic type with a tagged parent.
+	(Try_Object_Operation): Extensive rewriting, to handle properly various
+	overloading cases, when several ancestors may have class-wide operations
+	that are possible candidates, and when the overloaded functions return
+	array types and have defaulted parameters so that the call may be

+	(Analyze_Allocator): Remove Mark_Allocator and its invocation.
+	(Process_Function_Call): use Next, rather than Next_Actual, to analyze
+	successive actuals before analyzing the call itself.
+	(Try_Primitive_Operation): A primitive operation is compatible with the
+	prefix if the prefix has a synchronized type and the type of the formal
+	is its corresponding record, as can be the case when the primitive
+	operation is declared outside of the body of the type.
+	(Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
+	perform homonym traversal, looking for class-wide operation matches
+	(formerly done in statements of Try_Class_Wide_Operation). Matches on

+	(Mark_Allocator): An allocator with a discriminant association parent is
+	a coextension.
+	(Try_One_Prefix_Interpretation): If the type of the object is

+	When processing a primitive of a concurrent type which implements an
+	interface change the type of all controlling formals to that of the
+	corresponding record type.
+	(Check_Synchronized_Overriding): Relax the conditional logic when trying
+	to determine the tagged type to which a primitive belongs.
+	(Check_Conventions): Capture condition to ignore a primitive operation
+	(which is shared between the loop in Check_Conventions and the one in

+	controlling result when determining whether to add a BIP_Alloc_Form
+	formal and a BIP_Final_List formal to the function.

+	(Analyze_Subprogram_Body): If the return type of a function is an
+	anonymous access to the limited view of a class-wide type, and the
+	non-limited view of the type is available, update the type of the
+	function so that code can be generated.
+	(Process_Formals): In case of access-subtype itype whose designated
+	type is also an itype (situation that happens now with access to
+	subprograms) we mark the access-type itype with the Has_Delayed_Freeze
+	attribute to avoid backend problems.
+	(Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
+	init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
+	anonymous types' designated types are same before testing
+	Subtypes_Statically_Match.
+	(Create_Extra_Formals): Test for a named access parameter that is a
+	controlling formal as an additional condition for adding an
+	accessibility level formal. This can occur in the subp type created for
+	dispatching calls in Expand_Dispatching_Call, and allows calling
+	Create_Extra_Formals from that procedure rather than special-casing the
+	extra formals there.
+	(Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
+	when the function has a controlling result.
+	(Check_Returns): Add much more knowledge of the optimization of local
+	raise statements to gotos, to retain proper warnings in this case.
+	(Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
+	nodes when looking for last statement.

+	before the return is executed.
+	(Gen_Assign): Do not generate a call to deep adjust routine if the

+	(Is_Local_Access_Discriminant): Removed.
+	(Rewrite_Coextension): New routine which rewrites a static coextension
+	as a temporary and uses its unrestricted access in the construction of

+	(Complete_Coextension_Finalization): New routine. Generate finalization
+	attachment calls to all delayed coextensions.
+	(Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
+	the allocator is not a coextension itself and has delayed coextensions.
+	If the current allocator is controlled, but also a coextension, delay
+	the generation of the finalization attachment call.
+	Rename local variable "Node" to "Nod" in order to avoid confusion with
+	"Elists.Node".
+	(Expand_Allocator_Expression): Call Adjust for initialized allocators of
+	limited types that are not inherently limited. Such an allocator is
+	illegal, but is generated by the expander for a return statement, to
+	copy the result onto the secondary stack. This is the only case where a
+	limited object can be copied. Generate code to displace the pointer
+	to the object if the qualified expression is a class-wide interface
+	object. Such displacement was missing and hence the copy of the object
+	was wrong.
+	(Apply_Accessibility_Check): Handle allocated objects initialized in
+	place.
+	(Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
+	and Expand_Allocator_Expression. Allocating class-wide interface objects
+	this routine displaces the pointer to the allocated object to reference
+	the component referencing the corresponding secondary dispatch table.
+	Expand_Allocator_Expression): Add missing support to allocate class-wide
+	interface objects initialized with a qualified expression.
+	(Get_Allocator_Final_List): Test for an anonymous access type that is a
+	function result type, and use the finalization list associated with the

+	(Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
+	properly the case of a function whose return type is a limited
+	class-wide interface type. Modify the code of the accessibility
+	check to handle class-wide interface objects. In this case we need to
+	displace "this" to reference the primary dispatch table to get access
+	to the TSD of the object (to evaluate its accessibility level).
+	(Expand_N_Extended_Return_Statement): Test for a tagged result type
+	rather than a controlling result as one of the conditions for
+	generating tests of the implicit BIP_Alloc_Form formal. The
+	initialization assignment is also handled according to whether the
+	result is tagged instead of controlling.
+	In the case where the init assignment is inserted in the "then" part of
+	the allocation conditional, rewrite the target to be a dereference of
+	the implicit BIP_Object_Access formal.
+	If the returned value is unconstrained and created on the secondary
+	stack, mark the enclosing block and function so that the secondary
+	stack is not reclaimed on return.
+	Treat returns from functions with controlling results similarly to
+	returns from functions with unconstrained result subtypes.
+	If the object returned is unconstrained, and an allocator must be
+	created for it, analyze the allocator once the block for the extended
+	return is installed, to ensure that finalizable components
+	of the expression use the proper finalization list. Guard the call to
+	Move_Final_List with a check that there is something to finalize.
+	(Make_Tag_Ctrl_Assignment): Use "old" handling
+	of controlled type assignment for virtual machines, since new code uses

+	object.
+	(Expand_Inline_Call): If an actual is a literal, and the corresponding

+	value.  If the return type is a limited interface, do not treat the
+	return value as Controlled.
+	(Is_In_Place_Function):  If the return type is a limited interface,

+	(Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the

+	(Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged

+	(Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
+	rather than Is_Controlled and Has_Controlled_Component, since we want to
+	include class-wide result types in this treatment. Also test for a
+	controlling result, since that also requires passing a finalization
+	list.
+	(Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
+	even when the result subtype is constrained, to handle calls involving
+	controlling results.
+	(Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
+	is now called even when the result subtype is constrained, to handle

+	(Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
+	on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure

+	(Make_Build_In_Place_Call_In_Object_Declaration):
+	Add_Alloc_Form_Actual_* is now called even when the result subtype is

+	(Add_Return): Accomodate rewritten pattern from local raise to goto
+	transformation, so that we still recognize an transfer statement
+	and do the right thing here in that case.
+	(Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
+	and end of subprogram code.
+	(Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
+	support for primitives that are functions (without formals) with a

+	(Inherited_From_Formal): If the actual subtype has not generic parent
+	type, it is not an actual for a formal derived type, and there is no

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

+	Is_RAS.
+	(Append_RACW_Bodies): New subprogram.
+	(Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
+	Add_Receiving_Stubs_To_Declarations functions.
+	When expanding a package body, this list correspond to the
+	statements in the HSS at the end of the pacakge.
+	When expanding a package spec, this list correspond to the

+	registering the receiving stubs at the end of the 'Stmts' list.
+	(RCI_Package_Locator): Pass the new Version generic formal when
+	instantiating a RCI_Locator package.
+	(Build_From_Any_Function): To compute the High bound for an
+	unconstrained array actual, we add the Low bound with the length.
+	Thus we must convert the low bound and the length to an appropriate
+	type before doing the sum.
+	(Build_Subprogram_Receiving_Stubs, PolyORB):
+	 * Retrieve the extra formals parameters at the
+	   end of the parameter stream.
+	 * Use Move_Any_Value to write back out parameters

+	(TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,

+	typecode from the Etype. Therefore we retrieve the correct typecode
+	with a call to Get_Any_Type.
+	(Copy_Specification): Do controlling formal type substitution based on
+	Is_Controlling_Formal flag, instead of caller-provided object type.
+	(Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
+	a RACW primitive operation, we might get a subprogram declaration for an
+	ancestor of the RACW designated type (not for the designated type
+	itself), in the case where this operation is inherited. In this case we
+	have no easy means of determining the original tagged type for which
+	the primitive was declared, so instead we now rely on
+	Copy_Specification to use the Is_Controlling_Formal flag to determine
+	which formals require type substitution.

+	discrete types beyond Integer.
+	(Process_Default): Copy directly the unmatched formal. A generic copy
+	has already been performed in Analyze_Formal_Package.
+	(Analyze_Associations): If a formal subprogram has no match, check for
+	partial parametrization before looking for a default, to prevent
+	spurious errors.
+	(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
+	not set the instantiation environment before analyzing the actuals.
+	Fixes regression on 8515-003 with implementation of AI-133.
+	Set_Instance_Env checks whether the generic unit is a predefined
+	unit, in which case the instance must be analyzed with the latest Ada

+
+	* sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
+	prefix type is a discriminated subtype of the type of the formal.
+	(Analyze_Allocator): Collect all coextensions regardless of the context.
+	Whether they can be allocated statically is determined in exp_ch4.
+	(Analyze_Selected_Component): If the prefix is a limited view and the
+	non-limited view is available, use the non-limited one.
+	(Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
+	therefore illegal), suggest a qualified expression rather than a type
+	conversion, because a type conversion would be illegal in this context.
+	(Anayze_Allocator): Trace recursively all nested allocators so that all
+	coextensions are on the corresponding list for the root. Do no mark
+	coextensions if the root allocator is within a declaration for a stack-
+	allocated object, because the access discriminants will be allocated on
+	the stack as well.
+	(Analyze_Call): Remove restriction on calls to limited functions for the
+	cases of generic actuals for formal objects, defaults for formal objects
+	and defaults for record components.
+	(Analyze_Allocator): Before analysis, chain coextensions on the proper
+	element list. Their expansion is delayed until the enclosing allocator
+	is processed and its finalization list constructed.
+	(Try_Primitive_Operation): If the prefix is a concurrent type, looks
+	for an operation with the given name among the primitive operations of
+	the corresponding record type.
+	(Analyze_Selected_Component): If the prefix is a task type that
+	implements an interface, and there is no entry with the given name,
+	check whether there is another primitive operation (e.g. a function)
+	with that name.
+	(Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
+	properly the indexing of a function call written in prefix form, where
+	the function returns an array type, and all parameters of the function
+	except the first have defaults.
+	(Analyze_Equality_Op): If this is a call to an implicit inequality, keep
+	the original operands, rather than relocating them, for efficiency and
+	to work properly when an operand is overloaded.
+	(Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
+	Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
+	(Analyze_Selected_Component): If the prefix is a private extension, only
+	scan the visible components, not those of the full view.
+	(Try_Primitive_Operation): If the operation is a procedure, collect all
+	possible interpretations, as for a function, because in the presence of
+	classwide parameters several primitive operations of the type can match
+	the given arguments.

+	    Robert Dewar  <dewar@adacore.com>
+

+	    Thomas Quinot  <quinot@adacore.com>
+
+	* sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move

+	(Analyze_Package_Declaration): When the package declaration being
+	analyzed does not require an explicit body, call Check_Completion.
+	(May_Need_Implicit_Body): An implicit body is required when a package
+	spec contains the declaration of a remote access-to-classwide type.
+	(Analyze_Package_Body): If the package contains RACWs, append the
+	pending subprogram bodies generated by exp_dist at the end of the body.
+	(New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
+	Is_Abstract_Subprogram and Is_Abstract_Type.
+	(Preserve_Full_Attributes): The full entity list is not an attribute
+	that must be preserved from full to partial view.
+
+	* sem_dist.adb (Add_RAS_Dereference_TSS):
+	Change primitive name to _Call so it cannot clash with any legal
+	identifier, and be special-cased in Check_Completion.
+	Mark the full view of the designated type for the RACW associated with
+	a RAS as Comes_From_Source to get proper view switching when installing
+	private declarations.
+	Provite a placeholder nested package body along with the nested spec
+	to have a place for Append_RACW_Bodies to generate the calling stubs
+	and stream attributes.

+	(Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
+	rather than local Same_Formal_Type, to check whether protected operation

+	has a type that is a generic actual.
+	(Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
+	predicate Is_Concurrent_Type. This ensures supportin case of subtypes.

+	concurrent record type.
+	(Interface_Present_In_Parent): New subprogram used to check if a
+	given type or some of its parents implement a given interface.
+	(Collect_Abstract_Interfaces): Add support for concurrent types
+	with interface types.
+	(Has_Abstract_Interfaces): Add support for concurrent types with
+	interface types.
+	(Is_Parent): New subprogram that determines whether E1 is a parent
+	of E2. For a concurrent type its parent is the first element of its
+	list of interface types; for other types this function provides the
+	same result than Is_Ancestor.
+	(Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
+	(Collect_Synchronized_Interfaces): Removed because the subprogram
+	Collect_Abstract_Interfaces provides this functionality.
+	(Collect_Abstract_Interfaces): Minor update to give support to
+	concurrent types and thus avoid undesired code duplication.
+	(Get_Subprogram_Entity): Handle entry calls.
+	(May_Be_Lvalue): Include actuals that appear as in-out parameters in

+	(Case_Statement_To_gnu): If an alternative is an E_Constant with an

+	representing the choice value to ensure the corresponding GCC tree is
+	of the proper kind.
+	(maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
+	instead of just the operands, as the base GCC stabilize_reference does.
+	<CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
