A linker must do more than produce a runnable file. Follow the engineering behind parallel passes, deterministic output, useful diagnostics, layered tests, and incremental linking—and see how each optimization changes what must be proved.

Watch a cross-file call disappear, inspect the contract between symbol resolution and LTO, measure ThinLTO caching, then explore identical code folding and function layout without confusing smaller output with correct or faster output.
