摘要

本文描述了GCC （GNU编译器集合）编译器团队在鲲鹏920平台上改进CPUBench测试性能的工作结果。在性能分析期间，发现了某些缺陷，通过修改GCC编译器可以消除这些缺陷。总的来说，openEuler GCC中引入了大约10个优化。其中一些改进了现有的优化，而另一些则是独立的优化过程。这项工作的结果是，CPUBench整数测试包在单核运行时的性能提高了12%以上，在多核运行时的性能提高了11%以上，单个测试的性能提高了74%，SPEC CPU 2017整数包的性能提高了1.4%左右。

Development of GCC Optimizations to Speed up CPUBench Integer Benchmarks on ARMv8.2

This article describes the result of work by the GCC (GNU compiler collection) compiler team to improve the performance of CPUBench tests on the Kunpeng 920 platform. During performance analysis, certain deficiencies were discovered, which were eliminated by modifying the GCC compiler. Overall, around 10 optimizations were introduced to openEuler GCC. Some of them improve the existing optimizations, while others are independent optimization passes. The result of the work was an improvement in the performance of the CPUBench integer test package by more than 12% on single-core run and more than 11% on multi-core run, with an improvement of individual tests up to 74%, as well as an improvement of the SPEC CPU 2017 integer package by around 1.4%.
