sem_ch8.adb (Available_Subtype): Optimization in Find_Selected_Component...

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.
