| // module_comparer.h: ModuleComparer reads a string format of symbol file, and |
| // loads the symbol into both BasicSourceLineResolver::Module and |
| // FastSourceLineResolve::Module. It then traverses both Modules and compare |
| // the content of data to verify the correctness of new fast module. |
| // ModuleCompare class is a tool to verify correctness of a loaded |
| // FastSourceLineResolver::Module instance, i.e., in-memory representation of |
| // parsed symbol. ModuleComparer class should be used for testing purpose only, |
| // e.g., in fast_source_line_resolver_unittest. |
