Improving code generation time with C++ Build Insights

Kevin Cadieux July 21, 2020 Jul 21, 2020 07/21/20

Code generation time is a significant contributor to total build time for optimized builds. During this step of the compilation process, source code is passed through several algorithms that transform your program into an optimized version that can be executed more efficiently. In general, the optimization of a C++ function happens quickly and...
