longDescription = ''
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.
