往复式编译优化技术的新进展

计算机体系结构的不断演进使现代计算环境日益复杂化.这要求编译优化能够在充分利用硬件特性的同时适应适应这一演进.往复式编译优化技术通过对程序施以不同的转换并根据试运行的结果来指导对大而复杂的优化空间的搜索,有关研究表明适当的搜索算法可以找到其中好的点,从而显著提高程序运行性能.本文介绍了这项技术的基本思路和实现技术,简要回顾当前该领域内的前沿研究工作,并结合作者的相关经验,深入讨论其未来发展方向.

Techniques and Latest Progress of Iterative Optimizing Compilation

The rapid rate of architectural change and the sheer complexity of modern computing environment place enormous stress on compiler technology to both exploit complex hardware features and adapt to architectural change.To meet this demand,modern compiler uses iterative optimization to explore a large and complex program optimization space in search for performance improvement opportunity.Experimental results show that it can achieve significant performance improvement.This paper introduces the fundamental ide...
