可执行代码级优化器生成框架

Executable optimizer generation framework

编译基础设施生成的编译器对与目标机特征相关的优化支持不足 ,同时嵌入式应用系统的发展要求高质量的目标代码 ,为此 ,提出一种可执行代码级优化器生成框架EOGF (executable optimizer generation framework) ,以及该框架的关键支撑技术。与现有的编译器生成工具相结合 ,如 GCC(GNU com piler collection) ,可以实现高质量编译器的快速开发 ,并可以方便地充分利用目标机特点进行相关优化 ,提高目标代码质量。实验结果证明 ,EOGF是一个简便。

Present compilers generated by compiler infrastructures give insufficient support of architecture related optimizations. An executable optimizer generation framework (EOGF) was developed, which gives improved code quality for embedded application systems. With compiler infrastructures such as GCC (GNU compiler collection), the EOGF can quickly compose an integrated generation environment for high quality compilers. The EOGF can also improve the final code quality by taking advantage of the special machine characteristics. Experimental results show that the EOGF can flexibly and efficiently generate executable optimizers.
