32位浮点RISC嵌入式微处理器LS-C编译程序寄存器分配实现

Implementation of Register Allocation in LS-RISC Embedded Micro Processor LS-C Compiler

寄存器的合理利用是提高编译程序目标代码效率的关键因素。论文提出变量使用频度最低思想并详细阐述了其在32位浮点RISC嵌入式微处理器LS-C编译程序寄存器分配方案中的具体实现。

It is a key factor for effective object co de in compiler that the authors can utilize register with reason.This paper put s forward least used counts idea,and explains distinctly its ways and implement ation in LS-RISC embedded MicroProcessor LS-C compiler.
