+      <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 aims to be compatible with the common
+	linkers used for each file format.  For ELF this is the GNU
+	Binary File Descriptor (BFD) ld and GNU gold.  However, LLD's
+	authors are not constrained by strict compatibility where it
+	would hamper performance or desired functionality.</p>
+
+      <p>LLD developers made significant progress over the last
+	quarter.  With changes committed to both LLD and &os; we
+	reached a major milestone: it is now possible to link the
+	entire &os;/&amd64; base system (kernel and userland world)
+	with LLD.</p>
+
+      <p>Now that the base system links with LLD, we have started
+	investigating linking applications in the ports tree with LLD.
+	Through this process we are identifying limitations or bugs in
+	both LLD and a number of &os; ports.  With a few
+	work-in-progress patches we can link approximately 95% of the
+	ports collection with LLD on &amd64;.</p>
