            Bug ID: 24822
           Summary: llvm-symbolizer should fall back to the export list
                    when no symbol table is present
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: DebugInfo
          Assignee: david.majnemer at gmail.com
          Reporter: rnk at google.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

When no PDB and no mingw-style symbol table is present in the PE, dbghelp will
use the export table to try to answer addr2line requests. llvm-symbolizer uses
.dynsym for ELF, so we should do the same for COFF. I took a shot at this, but
it's not trivial because the types don't line up. We need to be able to form
SymbolRefs from export table entries.
