-<li>The LLVM code generator is now being <a

-<li>There is a new tool, llvm-abcd, the Analysis of ByteCode Dumper (abcd).
-This tool can compute basic statistics and bytecode density statistics on a
-module or function basis and also dump out bytecode in a textual format that
-is lower level than assembly (values are not resolved from slot numbers).
-It should only be of interest to (a) those who are working to improve the
