Research of Compiler Optimization Technology Based on Predicated Code
基于谓词代码的编译优化技术研究

A lot of branch instructions in program severely restrict the exploiting of parallelism of the architecture and the compiler.One of the major challenges to exploit effectively instruction level parallelism is overcoming the limitations imposed by branch instructions.Predicated execution can effectively delete branch instructions,and convert branch instructions to predicated code,which enlarges instruction scheduling scope and removes branch misprediction penalties.This paper described compiler optimization ...
