LLD is a linker from the LLVM project that is a drop-in replacement for
system linkers and runs much faster than them. It also provides features
that are useful for toolchain developers.

The linker supports ELF (Unix), PE/COFF (Windows), Mach-O (macOS) and
WebAssembly in descending order of completeness. Internally, LLD
consists of several different linkers. The PE/COFF port is complete,
including Windows debug info (PDB) support. The WebAssembly port is
still a work in progress (See WebAssembly lld port). The Mach-O port is
built based on a different architecture than the others. For the details
about Mach-O, please read ATOM-based lld.
