      GCC for openEuler User Guide

      The GCC for openEuler compiler is developed based on the open source GNU compiler Collection (GCC). The open source GCC is the de facto standard of cross-platform compilers, and it complies with the GPLv3 license, becoming the most widely used C/C++ compiler on Linux. GCC for openEuler inherits capabilities of the open source GCC. It also has optimizations on C, C++, and Fortran languages and delivers enhanced features such as automatic feedback-directed optimization (FDO), software and hardware collaboration, memory optimization, and automatic vectorization. GCC for openEuler is compatible with a wide range of hardware platforms such as Kunpeng, Phytium, and Loongson, fully unleashing the computing power of these hardware platforms.
