llvm-mirror/tools/llvm-pdbdump/CompilandDumper.cpp
Zachary Turner 1a7a66bda7 [llvm-pdbdump] Rewrite dumper using visitor pattern.
This increases the flexibility of how to dump different
symbol types -- necessary for context-sensitive formatting of
symbol types -- and also improves the modularity by allowing
the dumping to be implemented in the actual dumper, as opposed
to in the PDB library.
