+<li>The LLVM code generator got a multitude of improvements:
+<ul>
+<li>It can now fold spill code into instructions on targets that support it.</li>
+<li>A generic machine code spiller/rewriter was added. It provides an API for
+global register allocators to eliminate virtual registers and add the
+appropriate spill code.</li>
+<li>The represenation of machine basic blocks got cleaned up and improved to
