	* exp_attr.adb (Expand_N_Attribute_Reference, case Input): When
	expanding a 'Input attribute reference for a class-wide type,
	do not generate a separate object declaration for the controlling
	tag dummy object; instead, generate the expression inline in the
	dispatching call. Otherwise, the declaration (which involves a
	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.

    • sem_ch8.adb (Available_Subtype): Optimization in Find_Selected_Component... · 95e00a3a 
      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.
