// fast_source_line_resolver_unittest.cc: Unit tests for FastSourceLineResolver.
// Two different approaches for testing fast source line resolver:
// First, use the same unit test data for basic source line resolver.
// Second, read data from symbol files, load them as basic modules, and then
// serialize them and load the serialized data as fast modules. Then compare

// 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.
