Hi,


        Induction idiom can be expressed as in:


              i = i * c1 + c2;


        where c1, c2 are loop invariants and hence can be treated as
constants.


        Unfortunately, the computation of successive values of `i' is done
        sequentially.


        My question is can we parallelize the expression to obtain
        upto N successive values of `i' simultaneously?
