	* exp_aggr.adb (Pass_Aggregate_To_Back_End): Renamed as
	Build_Back_End_Aggregate.
	(Generate_Aggregate_For_Derived_Type): Code cleanup.
	(Prepend_Stored_Values): Code cleanup.

2017-01-19  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch6.adb (Analyze_Expression_Function): Check for an
	incomplete return type after attempting to freeze it, so that
	other freeze actiona are generated in the proper order.

2017-01-19  Ed Schonberg  <schonberg@adacore.com>

	* sem_aggr.adb (Resolve_Aggregate): If the type is a string
	type, ie. a type whose component is a character type, and the
	aggregate is positional, do not convert into a string literal
	if the index type is not an integer type, because the original
	type may be required in an enclosing operation.

	* binde.adb, debug.adb: Enable new elaboration order algorithm
	by default. -dp switch reverts to the old algorithm.

2017-01-19  Hristian Kirtchev  <kirtchev@adacore.com>

	* sem_ch3.adb Add with and use clauses for Exp_Ch7.
	(Analyze_Declarations): Create the DIC and Invariant
	procedure bodies s after all freezing has taken place.
	(Build_Assertion_Bodies): New routine.
	* sem_ch7.adb Remove the with and use clauses for Exp_Ch7
	and Exp_Util.
	(Analyze_Package_Specification): Remove the
	generation of the DIC and Invariant procedure bodies. This is
	now done by Analyze_Declarations.
	* sem_disp.adb (Check_Dispatching_Operation): DIC and Invariant
	procedures are never treated as primitives.

2017-01-19  Yannick Moy  <moy@adacore.com>

	* frontend.adb: Analyze inlined bodies and check elaboration
	rules in GNATprove mode too.
	* sem_elab.adb (Delay_Element): Add Boolean component to save
	indication that call is in SPARK code.	(Check_Elab_Calls):
	Check elaboration rules in GNATprove mode, and correctly set
	the current value of SPARK_Mode.
	* lib-xref-spark_specific.adb
	(Add_SPARK_Xrefs): Simplify iteration over dereferences.

2017-01-19  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch4.adb (Expand_Concatenate): Do no enable overflow
	checks on the expression for the high bound of concatenation
	when checks are disabled, to suppress warnings about potential
	constraint errors in restricted runtimes.
