ada: Fix internal error on call with parameter of predicated subtype
The problem is that the predicated subtype does not inherit all the required
attributes of a string subtype with a static predicate.
gcc/ada/
* sem_ch3.adb (Analyze_Subtype_Declaration): Remove a short-circuit
for subtypes without aspects when it comes to predicates.
* sem_util.adb (Inherit_Predicate_Flags): Deal with private subtypes
whose full view is an Itype.
