45 LLD is a linker from the LLVM project that is a drop-in replacement for
46 system linkers and runs much faster than them. It also provides features
47 that are useful for toolchain developers.
48 The linker supports ELF (Unix), PE/COFF (Windows), Mach-O (macOS), and
49 WebAssembly in descending order of completeness. Internally, LLD consists
50 of several different linkers.
