** BEGIN proof description **
* Iteration = 0: 0 unfolded rule generated, 0 loop generated
* Iteration = 1: 9 new unfolded rule(s) generated, 1 new loop(s) generated
* Iteration = 2: 6 new unfolded rule(s) generated, 4 new loop(s) generated
The mode mergesort(o,i) is non-terminating because of the generated looping pair:
  ([mergesort([_0|[_1|_2]],_3) :- split([_1|_2],_4,_5), split([_0|_1],[_0|_2],_3) :- split(_1,_3,_2)], {split/3->(), mergesort/2->(1->_0)})
* All specified modes do not terminate: mergesort(o,i) 

** END proof description **
