Ah, so passing the non-aliasing-var to a function which takes a POINTER
argument, returning that pointer and modifying it in the function that
takes the non-aliasing-var is ok then?
The Fortran semantics seem unclear enough to me to doubt that there is a
clean orthogonal representation for the middle-end.
