There are three legislative models on twice assignment of creditor ′ s right: time priority, notice priority and register priority. 债权二重让与有让与优先主义、通知优先主义、登记优先主义三种立法模式。
We introduce the concept of conflict graph and divide the register allocation problem under such two-source-operand constraints into two sub problems: the bank assignment subproblem and the register allocation subproblem. 我们提出了冲突图概念,并把这种双操作数冲突约束下的寄存器分配问题分解为二个子问题:组指派子问题和寄存器分配子问题。
