2005-03-08  Javier Miranda  <miranda@adacore.com>
	    Robert Dewar  <dewar@adacore.com>
	    Thomas Quinot  <quinot@adacore.com>
	    Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

	* atree.ads, atree.adb: Add support for Elist24 field

	* atree.h: Fix wrong definition of Field27
	Add support for Elist16 field
	Add support for Elist24 field

	* einfo.ads, einfo.adb (Abstract_Interfaces,
	Set_Abstract_Interfaces): New subprograms.
	(Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
	subprograms.
	(Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of
	entities rather than a single node.
	(Is_Interface, Set_Is_Interface): New subprogram
	(First_Tag_Component): New syntesized attribute
	(Next_Tag_Component): New synthesized attribute
	(Write_Entity_Flags): Upgraded to write Is_Interface
	(Write_Field24_Name): Upgraded to write Abstract_Interfaces
	(Write_Field25_Name): Upgraded to write Abstract_Interface_Alias
	(Task_Body_Procedure): New subprogram to read this attribute.
	(Set_Task_Body_Procedure): New subprogram to set this attribute.
	(Has_Controlled_Component): Now applies to all entities.
	This is only a documentation change, since it always worked to apply
	this to other than composite types (yielding false), but now this is
	official.
	Update documentation on Must_Be_Byte_Aligned for new spec

	* tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
	exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
	uses of the Access_Disp_Table attribute to reference the first dispatch
	table associated with a tagged type. As
	part of the implementation of abstract interface types,
	Access_Disp_Table has been redefined to contain a list of dispatch
	tables (rather than a single dispatch table).
	Similarly, upgrade all the references to Tag_Component by the
	new attribute First_Tag_Component.
	(Find_Inherited_TSS): Moved to exp_tss.
	Clean up test in Expand_N_Object_Declaration for cases
	where we need to do a separate assignment of the initial value.
	(Expand_N_Object_Declaration): If the expression in the
	declaration of a tagged type is an aggregate, no need to generate an
	additional tag assignment.
	(Freeze_Type): Now a function that returns True if the N_Freeze_Entity
	is to be deleted.
	Bit packed array ops are only called if operands are known to be
	aligned.
	(Component_Equality): When returning an N_Raise_Program_Error statement,
	ensure that its Etype is set to Empty to avoid confusing GIGI (which
	expects that only expressions have a bona fide type).
	(Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
	determine the amount of data to be copied.

	* par.adb (P_Interface_Type_Definition): New subprogram that parses the
	new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
	    INTERFACE_TYPE_DEFINITION ::=
	      [limited | task | protected | synchronized] interface
	        [AND interface_list]

	* par-ch3.adb (P_Type_Declaration): Modified to give support to
	interfaces.
	(P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
	interfaces.
	(P_Interface_Type_Definition): New subprogram that parses the new
	syntax rule of Ada 2005 interfaces
	(P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
	messages by the correct RENAMES (quotes removed).

	* sem_prag.adb: Upgrade all the references to Tag_Component by the new
	attribute First_Tag_Component.

	* sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
	(Interface_List, Set_Interface_List): New subprograms.
	(Interface_Present, Set_Interface_Present): New subprograms.
	(Limited_Present, Set_Limited_Present): Available also in derived
	type definition nodes.
	(Protected_Present, Set_Protected_Present): Available also in
	record type definition and
	derived type definition nodes.
	(Synchronized_Present, Set_Synchronized_Present): New subprograms.
	(Task_Present, Set_Task_Present): New subprogram.
	(Task_Body_Procedure): Removed.
	(Set_Task_Body_Procedure): Removed.
	These subprogram have been removed because the attribute
	Task_Body_Procedure has been moved to the corresponding task type
	or task subtype entity to leave a field free to store the list
	of interfaces implemented by a task (for AI-345)
	Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
	(Null_Exclusion_Present): Change to Flag11, to avoid conflict with
	expression flag Do_Range_Check
	(Exception_Junk): Change to Flag7 to accomodate above change
	(Box_Present, Default_Name, Specification, Set_Box_Present,
	Set_Default_Name, Set_Specification): Expand the expression
	"X in N_Formal_Subprogram_Declaration" into the corresponding
	two comparisons. Required to use the csinfo tool.

	* exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
	"with string" given.

        * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
        expression given.

	* par-ch11.adb (P_Raise_Statement): Recognize with string expression
	in 2005 mode

	* exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
	attribute Task_Body_Procedure rather than the old semantic field that
	was available in the task_type_declaration node.

	* par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
	interface type definitions.
	(P_Formal_Derived_Type_Definition): Modified to handle the list of
	interfaces.

	* par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
	task type declaration.
	(P_Protected): Modified to handle the list of interfaces in a
	protected type declaration.
