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.
