mold: A Parallel Linker

Mold is a new Unix/Linux linker that uses data parallelism across its entire pipeline to dramatically speed up the linking process, a major bottleneck in software builds. By redesigning the linker from scratch to decouple entangled operations like symbol resolution and archive processing, mold achieves 2.4-16.1x faster linking than the state-of-the-art lld linker and up to 112x faster than GNU ld, linking multi-gigabyte debug binaries in seconds or less.
