C++ in Huge AAA Games
summary
Codebase compiles into a single executable with millions of lines (3.5M+C++ for one game), and iteration time targets are concrete: distributed building gives 3–5 minute edit‑compile cycles via FastBuild with unity builds and network caching. Engineering choices are specific: no exceptions, custom reflection, own containers (not std::vector), OB1 minimal inlining for faster debug targets, global singletons via static buffers, generated code and an object analyzer to find hot template bloat, memory tagging and frame allocators to eliminate fragmentation.
