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