基于重定位的快速寻址链接优化OA

Presently,the majority of compiler optimization techniques primarily concentrate on the compilation phase,while optimization methods during the linking stage remain relatively scarce.This imbalance in focus has led to challenges in achieving optimal performance on certain specialized processor architectures.To address this predicament,a relocation-based link optimization for fast addressing approach is proposed in this research,encompassing three distinct optimization strategies:module-external global variable optimization,function jump optimization,and dynamic mode to static mode optimization.These strategies are meticulously designed to reduce memory access overhead,diminish instruction execution time,and alleviate the complexity associated with maintaining thread-local storage blocks.Experimental evaluations conducted on the SPEC 2006 benchmark demonstrate that when applied to the domestic Sunway processor,the proposed method achieves an average performance improvement of 3.66%and 1.50%,respectively on the SPECint 2006 and SPECfp 2006 benchmarks.
