So what addIntervalsToSpills returns are new intervals to allocate with infinite weights, right? And I need not to allocate the old interval. Should hasStackSlot return true on its register then?

Hello. I am making a backend for a virtual machine. But it does assume infinite number of virtual registers unlike those of usual machines. In this case, how can I implement this? Would you mind telling me some tips? Thank you so much. Seung Jae Lee
