-<li>MemOperand in the code generator: describe me!.</li>
+<li>The code generator now has support for carrying information about memory
+ references throughout the entire code generation process, via the
+ <a href="http://llvm.org/doxygen/classllvm_1_1MachineMemOperand.html">
+ MachineMemOperand</a> class. In the future this will be used to improve

<li>The target-independent code generator infrastructure now uses LLVM's APInt
class to handle integer values, which allows it to support integer types
