	Ada.Containers.Vectors to Ada.Containers. Later we can share it
	with other containers.

	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).

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

	* sem_ch3.adb (Is_Visible_Component): Component is visible
	in a derived type if inherited through an ancestor that has a
	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>

	underlying full view as well, for proper gdb display.

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

	* 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

	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.

	* 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>

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.

	* sem_ch4.adb (Analyze_Explicit_Dereference): The use of a limited

	Element_Access, Get_Element_Access declarations, we invoke the
	optimization.

	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.

	call to String'Input, returning a dynamically sized value on the
	secondary stack) will be expanded outside of proper secondary
	stack mark/release operations, and will thus cause a secondary
	stack leak.

	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.

	types (since they share the primary dispatch table).

2015-01-06  Vincent Celier  <celier@adacore.com>

	result to be 1.
