Practical Guide to GCC Link Time Optimization (LTO): Enhancing C++ Performance
Introduction When optimizing the performance of C++ projects, we often enable -O2 or -O3 to enhance the compilation optimization level. However, many developers are unaware that GCC’s Link Time Optimization (LTO) is a powerful technique that breaks the boundaries of object files, enabling cross-file function inlining and the removal of unused code, further improving program … Read more
