-  <li>A generic machine code spiller/rewriter was added. It provides an API for

-<li>LLVM now includes a new interprocedural optimization that converts small "by reference" arguments to "by value" arguments, which often improves the performance of C++ programs substantially.</li>
-<li>Bugpoint can now do a better job reducing miscompilation problems by
-reducing programs down to a particular loop nest, instead of just the function
-being miscompiled.</li>
