WebAbstract. We present a simple algorithm for register allocation which is competitive with … WebWell-suited for both caller-and calle-save registers, our strategy employs a “lazy” save mechanism that avoids saves for all effective leaf routines, an “eager” restore mechanism that reduces the effect of memory latency, and a “greedy” register shuffling algorithm that does a remarkbly good job of minimizing the need for ... download fifa 2007 demo
