 What's new in ELF Support?
 ==========================
 
+LLD 3.9 is a major milestone for us. It is the first release that can
+link real-world large userland programs, including LLVM/Clang/LLD
+themselves. In fact, it can now be used to produce most userland
+programs distributed as part of FreeBSD. Many contributors have joined
+to the project to develop new features, port it to new architectures
+and fix issues since the last release.
+
+LLD 3.9 is as fast as it was. That is, roughly speaking, 2x faster
+than GNU gold.

+Building LLVM toolchain with LLD
+--------------------------------
+
+A new CMake variable, ``LLVM_ENABLE_LLD``, has been added to use LLD
+to build the LLVM toolchain. If the varaible is true, ``-fuse-ld=lld``
+option will be added to linker flags so that ``ld.lld`` is used
+instead of default ``ld``.  Because ``-fuse-ld=lld`` is a new compiler
+driver option, you need Clang 3.8 or newer to use the feature.
