ada: Reject thin 'Unrestricted_Access value to aliased constrained array
This rejects the Unrestricted_Access attribute applied to an aliased array
with a constrained nominal subtype when its type is resolved to be a thin
pointer. The reason is that supporting this case would require the aliased
array to contain its bounds, and this is the case only for aliased arrays
whose nominal subtype is unconstrained.
gcc/ada/
* sem_attr.adb (Is_Thin_Pointer_To_Unc_Array): New predicate.
(Resolve_Attribute): Apply the static matching legality rule to an
Unrestricted_Access attribute applied to an aliased prefix if the
type is a thin pointer. Call Is_Thin_Pointer_To_Unc_Array for the
aliasing legality rule as well.
