+      <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>
