【摘要】 本文提出的寄存器分配策略,通过判断高级微语言中每一个变量的类型和使用范围,给目标机所有的寄存器设置一个特征值,并通过该特征值来判定各个寄存器的使用情况,从而得出对寄存器进行再分配的优先顺序。更多还原

【Abstract】 A register allocation scheme is proposed. In this approach, we use an RCV (Register Characteristic Value) to represent the use state of a register. The RCV is varied according to the type and the effective scope of the variable in the register. The priority of the register allocation is based upon the RCV’s of every register.更多还原
