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

2007-04-06  Robert Dewar  <dewar@adacore.com>

	(No_Exception_Propagation) is set and in any case make the associated
	handler unsuitable as a target for a local raise statement.
	(Expand_Dispatching_Constructor_Call): Replace generation of call to the
	run-time subprogram CW_Membership by call to Build_CW_Membership.

2007-04-06  Thomas Quinot  <quinot@adacore.com>

	* exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
	Do an Unchecked_Conversion to handle the passage from the Underlying
	Type to the Base Type when calling Build_To_Any_Call and
	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.
	(PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
	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
	spec declarations.
	(Add_Receiving_Stubs_To_Declarations): Append the function
	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
	   after executing the request as it is more efficient
	   than Copy_Any_Value.
	 * Build the any containing Extra Formals with the
	   appropriate typecode.
	(PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
	empty Component_List.
	(Build_Actual_Object_Declaration): New subprogram. Build and insert into
	the tree the declaration for an object that serves as actual parameter
	in server-side stubs.
	(GARLIC_Support.Build_Subprogram_Receiving_Stubs,
	PolyORB_Support.Build_Subprogram_Receiving_Stubs):
	Use Build_Actual_Object_Declaration to prepare the actuals.
	(Add_Parameter_To_NVList): Set the parameter mode to In for
	Extra Constrained Parameters.
	(Build_General_Calling_Stubs): Set the parameter type to boolean for
	Extra Constrained parameters.
	(Build_To_Any_Function, Build_From_Any_Function,
	Built_TypeCode_Function): When Typ is implicit, call the correct
	function with the first not implicit parent type.
	(TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
	(FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
	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.

	(Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate

	a protected object, because they may be invoked through a callback.
	(Set_Privals): If the type of a private component is an anonymous access
	type, do not create a new itype for each protected body.
	If the body of a protected operation creates
	controlled types (including allocators for class-widetypes), the
	body of the corresponding protected subprogram must include a
	finalization list.
	(Build_Activation_Chain_Entity): Build the chain entity for extended
	return statements.
	(Type_Conformant_Parameters): Use common predicate Conforming_Types
	to determine whether operation overrides an inherited primitive.
	(Build_Wrapper_Spec): Add code to examine the parents while looking
	for a possible overriding candidate.
	(Build_Simple_Entry_Call): Set No_Initialization on the object used to

	accessibility on class-wide allocators if the allocator occurs at the
	same scope level as the allocator's type. The check is guaranteed to
	succeed in that case, even when the expression originates from a
	parameter of the containing subprogram.
	(Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
	under No_Dispatching_Calls restriction. During the semantic analysis
	we already notified such violation.
	(Tagged_Membership): Constant folding. There is no need to check
	the tag at run-time if the type of the right operand is non

	* exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to

	Modify the declaration of the object containing the TSD
	because we now expand code that has a higher level of abstraction.
	The TSD has a discriminant containing the Inheritance Depth Level,
	value that is used in the membership test but also to fix the size
	of the table of ancestors.
	(Expand_Interface_Conversion): Insert function body at the closest place
