+// 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
+// modules to assure the fast module contains exactly the same data as
+// basic module.
