+<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
