+    <body>
+      <p><tt>lld</tt> 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.  Where possible, <tt>lld</tt>
+	maintains command-line and functional compatibility with the
+	existing GNU BFD ld and gold linkers. However, the authors of
+	<tt>lld</tt> are not constrained by strict compatibility where
+	it would hamper performance or desired functionality.</p>
+
+      <p>Compared to the GNU ld 2.17.50 currently in the base system,
+	<tt>lld</tt> will bring:</p>
+
+      <ul>
+	<li>AArch64 (arm64) support</li>
+
+	<li>Link Time Optimization (LTO)</li>
+
+	<li>New ABI support</li>
+
+	<li>Other linker optimizations</li>
+
+	<li>Much faster link times</li>
+
+	<li>Maintained code base</li>
+      </ul>
+
+      <p>The upstream <tt>lld</tt> project has now implemented
+	nearly all of the functionality required to link the amd64
+	FreeBSD base system, including the kernel.  The boot loader
+	components and <tt>rescue</tt> utilities currently do not
+	build with <tt>lld</tt>.</p>
