New Revision: 58368

URL: http://llvm.org/viewvc/llvm-project?rev=58368&view=rev
Log:
Update FindSpecRefs to recognize named section references.
 - Unfortunately, I don't have an easy way to map from named sections
   to numbers nicely so they don't get page numbers or integrate in
   the list well.
