| 摘 要： | 通过分簇结构实现向量化执行是一种高效而灵活的体系结构选择.在编译中间表示里,向量指令与标量指令交叠出现.分簇结构向量化实现的特殊方式给传统的寄存器分配框架带来了挑战.针对该问题,本文从向量指令的表示形式、Callee/Caller寄存器划分、向量寄存器分配等进行研究,并给出全局与局部向量寄存器的分配方法.

| Abstract: | It is an efficient and flexible architecture choice to realize SIMD execution through clustering structure.And then the vector instructions probably come out together with the scalar instructions in the intermediate representation of compiler.The special way for SIMD impementation on clustering structure brings challenges to the traditional register allocation framework.To solve the problem,in the paper,the representation style of the vector instructions,the partition of Callee/Caller register,the vector register allocation are studied,and the global and local vector register allocation methods are proposed. |
