编译和链接程序时都必须使用 -fprofile-generate。 启用以下选项:-fprofile-arcs、-fprofile-values、-fvpt。 -fprofile-use 启用配置文件反馈定向优化,并且优化通常只有在配置文件反馈可用的情况下才有利可图。 启用以下选项:-fbranch-probabilities、-fvpt、-funroll-loops、-fpeel-loops、-ftracer。 以下选项控制...

最近在编译动态库文件,用到-fPIC编译选项。查了下GNU的手册: -fpic Generate position-independent code (PIC) suitable for use in a shared library, if supported for the target machine. Such code accesses all constant addresses through a global offset table (GOT). The dynamic loader resolves the GOT...
