	partial view of the original type holding the component, if the
	full view of that original type is in scope.
	* sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.

2015-05-28  Bob Duff  <duff@adacore.com>

	* sem_util.adb (Requires_Transient_Scope): For definite untagged
	subtypes, we should never have to use the secondary stack. This moves
	toward that goal. But there are still cases that don't work.
	Here, we move the check for Is_Definite first, but add a
	special-purpose check for Has_Discrim_Dep_Array.

2015-05-28  Bob Duff  <duff@adacore.com>

	* sem_util.adb (Requires_Transient_Scope): Avoid returning

	* sem_util.adb (Wrong_Type): In any instance, do not emit error
	if type of expression is the partial view of the expected type.

2015-05-28  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Resolve_Actuals): a)  The replacement of formal
	names in named associations only needs to be done within an
	instance, on a call to a primitive of a formal derived type,
	where the actual subprogram may have different formal names than
	those of the primitive operation of the formal type.
	b) Defaulted parameters must be taken into account when obtaining
	the names of the formals of the actual subprogram being called.

2015-05-28  Robert Dewar  <dewar@adacore.com>

	* sem_ch13.adb, sem_disp.ads: Minor reformatting.

2015-05-28  Ed Schonberg  <schonberg@adacore.com>

	* sem_util.adb (Set_Debug_Info_Needed): For a private type
	whose full view is itself a derived private type, set flag on
	underlying full view as well, for proper gdb display.

	* exp_tss.ads: Minor comment fix.
	* exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
	Inline init_procs when the type has controlled parts. Remove
	obsolete comments about those init_procs -- init_procs for
	such types are no longer complex. A typical init_proc just
	initializes the 'Tag field, and calls the parent init_proc
	(e.g. for Limited_Controlled), which calls the grandparent
	(for Root_Controlled), which does nothing. This all boils down
	to one instruction when inlined.
	* exp_ch7.adb (Create_Finalizer): Inline the finalizer.

2015-05-28  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Analyze_Selected_Component): If the type to use
	is a derived type and is a generic actual, the selected component
	appears within an instance body, and the check over the type
	has failed, examine ancestor types for the desired component.
	(Find_Component_In_Instance): If record type is a derived type,
	examine all ancestors in order to locate desired component.

2015-05-27  H.J. Lu  <hongjiu.lu@intel.com>

	* gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.

2015-05-27  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
	incomplete type coming from a limited_with and whose non-limited view
	comes from the main unit.

2015-05-27  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
	code applying atomic checks to the object.

2015-05-27  Robert Dewar  <dewar@adacore.com>

	* sem_aux.adb: Minor rewording.

2015-05-27  Bob Duff  <duff@adacore.com>

	opt.ads, s-bignum.adb, output.ads, sem_ch13.adb, erroutc.ads,
	sem_disp.ads, exp_ch3.adb: Minor fixes of duplicate words in comments.

	well as kernel.

	* par_sco.adb (Process_Decision): Store sloc to
	condition/pragmas SCOs associations into a temporary table before
	moving them to the SCO_Raw_Hash_Table so that we can back them
	out just like we do for SCO entries that are simple decisions
	in an expression context.

2015-05-27  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch6.adb (Process_Formals): A non-private formal type that
	is a limited view does not have a list of private dependents.

2015-05-27  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch5.adb (Expand_N_Case_Statement): If the expression in
	the case statement is a compile-time known value, we look for a
	corresponding alternative to optimize the case statement into a
	single case. If the type has a static predicate and the expression
	does not satisfy the predicate, there is no legal alternative and
	this optimization is not applicable.  Excecution is erroneous,
	or else if assertions are enabled, an exception will be raised
	earlier, at the point the expression is elaborated.

2015-05-27  Robert Dewar  <dewar@adacore.com>

	* sem_elab.adb (Check_Internal_Call_Continue): Suppress
	warning on Finalize, Adjust, or Initialize if type involved has

2015-05-26  Bob Duff  <duff@adacore.com>

	* sem_elab.adb (Check_A_Call): In the case where we're
	calling something in an instance of a generic package that is
	within this same unit (as the call), make sure we treat it
	as a call to an entity within the same unit. That is, call
	Check_Internal_Call, rather than putting "Elaborate_All(X)"
	on X, which would necessarily result in an elaboration cycle in
	static-elaboration mode.

2015-05-26  Eric Botcazou  <ebotcazou@adacore.com>

	* freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
	* freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity
	parameter into Node parameter and remove Type parameter.
	Look at Is_Atomic_Or_VFA both on the type and on the object.

	* gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
	force evaluation of the expression, if any, when the object has its
	elaboration delayed.  Do not create a variable at global level.

	has aspect specifications, examine the corresponding list of
	representation items to determine whether there is a visible
	stream operation. The attribute definition clause generated from
	the aspect will be inserted at the freeze point of the type,
	which may be in the private part and not directly visible,

	be performed.
	(Analyze_Call): Check if the flag must be set and if the outermost
	enclosing construct.
	* sem_util.adb (Check_Function_Writable_Actuals): Code cleanup

2015-05-22  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Resolve_Actuals): If the call is to an overridden

	Instead of doing literally what the RM calls for, we do something
	equivalent that avoids expensive operations inside the loop. If the
	container package has appropriate Next, Pseudo_Reference,
	Element_Access, Get_Element_Access declarations, we invoke the
	optimization.

	actual in an instance matches an incomplete formal.
	* sem_disp.adb (Check_Dispatching_Call): Handle missing case of

	and will fail if this with_clause is missing.  We place the
	instance body at the beginning of the enclosing body, which is
	the unit being compiled, and ensure that freeze nodes for the
	full views of the incomplete types appear before the instance.

	up. Pragmas Post, Post_Class, Postcondition, Pre, Pre_Class
	and Precondition now use the same routine for analysis. Pragma

	* sem_ch8.adb (Available_Subtype): Optimization in
	Find_Selected_Component: when safe, use existing subtype of

	* gnat1drv.adb: Minor: complete previous change.

2015-01-06  Olivier Hainque  <hainque@adacore.com>

	* set_targ.ads (C_Type_For): New function. Return the name of
	a C type supported by the back-end and suitable as a basis to
	construct the standard Ada floating point type identified by
	the T parameter. This is used as a common ground to feed both
	ttypes values and the GNAT tree nodes for the standard floating
	point types.
	* set_targ.adb (Long_Double_Index): The index at which "long
	double" gets registered in the FPT_Mode_Table. This is useful to
	know whether we have a "long double" available at all and get at
	it's characteristics without having to search the FPT_Mode_Table
	when we need to decide which C type should be used as the
	basis for Long_Long_Float in Ada.
	(Register_Float_Type): Fill Long_Double_Index.
	(FPT_Mode_Index_For): New function. Return the index in
	FPT_Mode_Table that designates the entry corresponding to the
	provided C type name.
	(FPT_Mode_Index_For): New function. Return the index in
	FPT_Mode_Table that designates the entry for a back-end type
	suitable as a basis to construct the standard Ada floating point
	type identified by the input T parameter.
	(elaboration code): Register_Back_End_Types unconditionally,
	so C_Type_For can operate regardless of -gnateT. Do it
	early so we can query it for the floating point sizes, via
	FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
	Long_Double_Size from the FPT_Mode_Table, as cstand will do.
	* cstand.adb (Create_Float_Types): Use C_Type_For to determine
	which C type should be used as the basis for the construction
	of the Standard Ada floating point types.
	* get_targ.ads (Get_Float_Size, Get_Double_Size,
	Get_Long_Double_Size): Remove.
	* get_targ.adb: Likewise.

	build function and operator wrappers after the actual subprogram
	has been resolved, and replace the standard renaming declaration
	with the declaration of wrapper.
	* sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
	make public for use elsewhere.
	* sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
