Getter function Predicated_Parent expects to be called on subtypes only,
which was not enforced always, possibly leading to assertion failures on
compiler built with assertions.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* sem_ch13.adb (Build_Predicate_Functions): Access
Predicated_Parent only on subtypes.
