+<p><b>Special note:</b> if you are debugging MultiSource or SPEC tests that
+already exist in the <tt>llvm/test</tt> hierarchy, there is an easier way to
+debug the JIT, LLC, and CBE, using the pre-written Makefile targets, which

 <p>At the end of a successful <tt>bugpoint</tt> run, you will be presented
 with two bytecode files: a <em>safe</em> file which can be compiled with the C
 backend and the <em>test</em> file which either LLC or the JIT
