	may produce spurious errors when the generic is a child unit
	that references entities in the parent (which might not be in
	scope at the freeze point of the instance).

	* a-contai.ads: Add two check names: Container_Checks and

	Ada.Containers.Vectors to Ada.Containers. Later we can share it
	with other containers.
	Disable the tampering machinery in the presence of
	Suppress(Tampering_Check).
	Simplify the implementation of tampering checks. E.g. use RAII
	to make incrementing/decrementing of the counts more concise.
	* a-contai.adb: New package body, implementing the above.
	* a-convec.ads, a-convec.adb: Use tampering check machinery
	in Ada.Containers.
	Disable all checking code when checks are suppressed.
	Simplify many of the operations. Implement "&" in terms of Append,
	rather than "by hand".
	Remove: function "=" (L, R : Elements_Array) return Boolean is
	abstract; so we can call the predefined "=" on Elements_Array.
	For "=" on Vectors: Previously, we returned True immediately if
	Left'Address = Right'Address.  That seems like a non-optimization
	("if X = X" is unusual), so removed that.  Simplify by using
	slice comparison ("=" on Element_Array will automatically call
	"=" on the components, even if user defined).

	* sem_ch3.adb (Is_Visible_Component): Component is visible

	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

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

	* 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.

	* 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

	(Find_Component_In_Instance): If record type is a derived type,
	examine all ancestors in order to locate desired component.

	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

	on X, which would necessarily result in an elaboration cycle in
	static-elaboration mode.

	prevent an infinite recursion, may be rewritten as a temporary
	by Remove_Side_Effects.  Ensure that the caller has access to
	the original function call to continue expansion.

	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,
	but the aspect makes the operation available to a client.

	* snames.ads-tmpl: New names referenced by exp_ch5.adb.

	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.

	full views of the incomplete types appear before the instance.

	(Insert_Pragma): Insertion in a subprogram body takes precedence over
	the case where the subprogram body is also a compilation unit.
	* sem_prag.adb (Analyze_Contract_Cases_In_Decl_Part): Use

2015-03-02  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch8.adb (Available_Subtype): Optimization in
	Find_Selected_Component: when safe, use existing subtype of
	array component, possibly discriminant-dependent, rather than
	creating new subtype declaration for it. In this fashion different
	occurrences of the component have the same subtype, rather than
	just equivalent ones. Simplifies value tracing in GNATProve.

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

	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.

	* sem_ch6.adb (New_Overloaded_Entity): In GNATprove mode, a

	* sem_ch8.adb (Analyze_Subprogram_Renaming): In GNATprove mode,
	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):
	rewrite, now that actual is fully resolved when wrapper is
	constructed.

	* sem_res.adb (Is_Assignment_Or_Object_Expression): New routine.

	if a 'access attribute is applied to the function, in which case
	last_entity may have been assigned already.

2015-01-06  Ed Schonberg  <schonberg@adacore.com>
