+ <p>LLD is the linker in the LLVM family of projects. It is a
+ high-performance linker that supports the ELF, COFF and
+ Mach-O object formats. It is broadly compatible with the
+ common linkers used for each file format. For ELF this is
+ the GNU Binary File Descriptor (BFD) <tt>ld</tt> and GNU
+ <tt>gold</tt>. However, LLD's authors are not constrained
+ by strict compatibility where it would hamper performance or
+ desired functionality.</p>
+
+ <p>LLD is now used as the default system linker for
+ &os;/arm64 and can link a working kernel, modules, and
+ userland for &os;/amd64. LLD can also link a working
+ kernel and modules (but not userland) for &os;/arm and
+ &os;/i386.</p>
+
+ <p>Work is ongoing to address ports that do not build with LLD
+ as the system linker (either by fixing the port, or
+ configuring the port to be linked by GNU <tt>ld</tt>).</p>
+
+ <p>For &os; 12.0 we expect to use LLD as the system linker for
+ the same set of architectures that use Clang by default:
+ 32- and 64-bit arm and x86.</p>
