2017-01-13  Javier Miranda  <miranda@adacore.com>

	* einfo.ads (Component_Bit_Offset): Fix documentation.
	* sem_ch13.adb (Check_Record_Representation_Clause): Skip check
	on record holes for components with unknown compile-time offsets.

2017-01-13  Bob Duff  <duff@adacore.com>

	* ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
	* g-locfil.ads: Minor comment fix.

2017-01-13  Bob Duff  <duff@adacore.com>

	* binde.adb (Elab_New): New elaboration order algorithm
	that is expected to cause fewer ABE issues. This is a work in
	progress. The new algorithm is currently disabled, and can be
	enable by the -dp switch, or by modifying the Do_Old and Do_New
	etc. flags and rebuilding. Experimental code is included to
	compare the results of the old and new algorithms.
	* binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
	can have multiple of these tables, so the old and new algorithms
	can coexist.
	* bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
	parameter of type array. This avoids the global variable, and
	allows bounds checking (which is normally defeated by the tables
	packages). It also ensures that the Elab_Order is read-only
	to Bindgen.
	* bindgen.adb: Pass Elab_Order as an 'in' parameter to all
	subprograms that need it, as above.
	* debug.adb: Document new -dp switch. Modify doc of old -do
	switch.
	* gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
	and Bindgen.  Move writing of closure (-R and -Ra switches)
	to Binde; that's more convenient.

2017-01-13  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch6.adb (Analyze_Expression_Function): If the expression
	function is a completion, all entities referenced in the
	expression are frozen. As a consequence, a reference to an
	uncompleted private type from an enclosing scope is illegal.

2017-01-13  Javier Miranda  <miranda@adacore.com>

	* sem_ch6.adb (Freeze_Expr_Types): New subprogram.
	(Analyze_Subprogram_Body_Helper): At the occurrence of an
	expression function declaration that is a completion, its
	expression causes freezing (AI12-0103).

2017-01-13  Vadim Godunko  <godunko@adacore.com>

	* a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
	Reference functions of Ada.Containers.Indefinite_Holders.

2017-01-13  Bob Duff  <duff@adacore.com>

	* s-os_lib.ads: Minor comment fixes.

2017-01-13  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_ch3.adb (Default_Initialize_Object): Do not default
	initialize an object when it is of a task type and restriction
	No_Tasking is in effect because the initialization is obsolete.
	* exp_ch9.adb (Build_Master_Entity): Do not generate a master when
	restriction No_Tasking is in effect.
	(Build_Master_Renaming): Do not rename a master when restriction
	No_Tasking is in effect.

2017-01-13  Ed Schonberg  <schonberg@adacore.com>

	* sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
	the legality of An others clause applies as well to a choice in
	an Iterated_component_ association.
	(Resolve_Iterated_Component_Association): An others choice
	is legal.
	* exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
	Iterated_Component_Association is not static.

2017-01-13  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
	control is passed to the expresion handler before the new mode
	is set.
	* sem_ch12.adb (Analyze_Package_Instantiation,
	Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
	in case control is passed to the expresion handler before the
	new mode is set.

2017-01-13  Hristian Kirtchev  <kirtchev@adacore.com>

	* sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,
	exp_aggr.adb: Minor reformatting.

2017-01-13  Gary Dismukes  <dismukes@adacore.com>

	* inline.adb: Minor reformatting and typo fix.

2017-01-13  Ed Schonberg  <schonberg@adacore.com>

	* sem_util.ads, sem_util.adb (Choice_List): Move function here
	from sem_aggr.adb, for use elsewhere.
	* sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
	* sem_aggr.adb (Resolve_Array_Aggregate): Remove
	Iterated_Component_Present.
	* exp_aggr.adb: Use Choice_List throughout, to handle
	Iterated_Component_Associations.
	(Gen_Loop): Generate proper loop for an
	Iterated_Component_Association: loop variable has the identifier
	of the original association. Generate a loop even for a single
	component choice, in order to make loop parameter visible in
	expression.
	(Flatten): An Iterated_Component_Association is not static.

2017-01-13  Yannick Moy  <moy@adacore.com>

	* exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
	float exponentiation for statically known small negative values
	is the reciprocal of the exponentiation for the opposite value
	of the exponent.
	* s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
	Ensure that the value of float exponentiation for negative values
	is the reciprocal of the exponentiation for the opposite value
	of the exponent.
	* inline.adb (Expand_Inlined_Call): Fix the count
	for the number of generated gotos.

2017-01-13  Yannick Moy  <moy@adacore.com>

	* inline.adb: Code cleanup.
	* sem_util.adb (Is_OK_Volatile_Context): Add
	expression in delay statement as OK for volatile context.

2017-01-13  Ed Schonberg  <schonberg@adacore.com>

	* sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
	mode a choice that is a subtype with a static predicate is
	replaced by the values it covers. This transformation must not
	be performed in ASIS mode, to preserve the source for analysis.

2017-01-13  Justin Squirek  <squirek@adacore.com>

	* nlists.ads: Correct minor typo.

2017-01-13  Gary Dismukes  <dismukes@adacore.com>

	* par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
	Iterated_Component_Association is a named association in an
	array aggregate.
	* sem_aggr.adb (Resolve_Iterated_Component_Association): New
	procedure, subsidiary of Resolve_Array_Aggregate, to analyze
	and resolve the discrete choices and the expression of the
	new construct.
	* sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
	Loop_Actions and Box_Present are attributes of
	N_Iterated_Component_Association nodes. Box_Present is always
	False in this case.
	* sprint.adb (Sprint_Node): An Iterated_Component_Association
	has a Discrete_Choices list, as specified in the RM. A
	Component_Association for aggregate uses instead a Choices list.
	We have to live with this small inconsistency because the new
	construct also has a defining identifier, and there is no way
	to merge the two node structures.

2017-01-13  Yannick Moy  <moy@adacore.com>

	* inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
	list of pragmas to remove.  Remove pragmas from the list of
	statements in the body to inline.
	* namet.adb, namet.ads (Nam_In): New version with 12 parameters.

2017-01-13  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
	Analyze_Declarations, to analyze and resolve the expressions of
	aspect specifications in the current declarative list, so that
	the expressions have proper entity and type info.  This is needed
	for ASIS when there is no subsequent expansion to generate this
	semantic information.
	* sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
	original expression, to suppress cascaded errors when expression
	has been constant-folded.
	(Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
	ASIS mode, because there is no subsequent expansion to decorate
	the tree.

2017-01-13  Yannick Moy  <moy@adacore.com>

	* inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
	New function to detect when a call may be inlined or not in
	GNATprove mode.
	(Expand_Inlined_Call): Ensure that a temporary
	is always created in the cases where a type conversion may be
	needed on an input parameter in GNATprove mode, so that GNATprove
	sees the check to perform.
	* sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
	when not applicable due to actual requiring type conversion
	with possible check but no temporary value can be copied for
	GNATprove to see the check.
