Link-Time Optimization
LTO defers optimization until link time, when the compiler sees every translation unit at once, enabling cross-module inlining and whole-program dead-code removal that per-file compilation cannot do. For Wasm targets it routinely cuts both size and runtime, at the price of slower builds.
This Concept is waiting for its first lesson!
