There is no loss of information: we go out of SSA only for scalar phi nodes that cannot be represented by scev: for each phi node we introduce an array with one element. These arrays are eliminated after graphite by a scalar cleanup and we obtain again the program in SSA form. Handling reductions in SSA form is not an option for the moment. Sebastian
