If you do

procedure F (S : in Unconstrained_Array);

V : Unconstrained_Array (-10_000 .. -1);
-- You must do things like this, since your index subtype is Integer.
-- If you intended only positive indices, surely you would use Positive.

F (S => V);

I know of no compiler that will not use pass by reference.
