Abstract: This paper carries out research on the key issues in retargeting and code implementation and develops an industrial quality compiler based on Open64 for embedded PowerPC architecture. According to the test result of gcc-c. torture and SPEC2000, this compiler is close to or reaches GCC on correctness and performance. This work provides good compiling tool support for future research and application, and lays a good foundation for the future work such as automatic retargeting.

Key words: compiler, retargeting, Open64 compiler, PowerPC

摘要： 基于开源高性能编译器Open64，以PowerPC嵌入式处理器为例，开展重定向关键问题研究和代码实现，自主开发完成一款具有工业产品水准的高性能开源编译器后端。gcc-c.torture和SPEC2000实测结果表明，在正确性和性能方面，该编译器均接近或达到和GCC编译器相当的水平，为进一步研究和应用提供良好的编译工具支持以及实现参考，同时为后续自动重定向等工作奠定基础。
