	* exp_ch11.adb: Minor reformatting.

2013-01-03  Thomas Quinot  <quinot@adacore.com>

	* exp_util.adb, einfo.adb, einfo.ads, freeze.adb, exp_aggr.adb,
	sem_ch13.adb (Einfo.Initialization_Statements,
	Einfo.Set_Initialization_Statements): New entity attribute
	for objects.
	(Exp_Util.Find_Init_Call): Handle case of an object initialized
	by an aggregate converted to a block of assignment statements.
	(Freeze.Check_Address_Clause): Do not clear Has_Delayed_Freeze
	even for objects that require a constant address, because the
	address expression might involve entities that have yet to be
	elaborated at the point of the object declaration.
	(Exp_Aggr.Convert_Aggregate_In_Obj_Decl): For a type that does
	not require a transient scope, capture the assignment statements
	in a block so that they can be moved down after elaboration of
	an address clause if needed.
	(Sem_Ch13.Check_Constant_Address_Clause.Check_Expr_Constants,
	case N_Unchecked_Conversion): Do not replace operand subtype with
	its base type as this violates a GIGI invariant if the operand
	is an identifier (in which case the etype of the identifier
	is expected to be equal to that of the denoted entity).

	* sem_util.ads, sem_util.adb (Denotes_Same_Object): Extend the
	functionality of this routine to cover cases described in the Ada 2012
	reference manual.

	* sem_elab.adb (Set_Elaboration_Constraint): Handle properly
	a 'Access attribute reference when the subprogram is called
	Initialize.

2013-01-03  Arnaud Charlet  <charlet@adacore.com>

	* s-tpobop.adb (PO_Do_Or_Queue): Refine assertion, since a
	select statement may be called from a controlled (e.g. Initialize)
	operation and have abort always deferred.
