|
|
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.
