From their readme:
> mold is a faster drop-in replacement for existing Unix linkers. It is several times faster than the LLVM lld linker, the second-fastest open-source linker which I originally created a few years ago. mold is designed to increase developer productivity by reducing build time, especially in rapid debug-edit-rebuild cycles.
Great to see that Mold now has support for LTO. Hope I can begin using it as my default linker in Arch soon.
