Google Test performs hidden test registration during process startup. For test binaries that contain a large number of tests, this registration can be costly. In this CL, we reduce the overhead of registration via several tactics: - Treat CodeLocation and FilePath as value types, using std::move to pass them around. - Reduce string copies in various places by either passing std::string values via std::move, or passing const-refs to std::string instances. - Use std::to_string to stringify an int in DefaultParamName rather than a std::stringstream. - Pull some std::string instances out of nested loops in ParameterizedTestSuiteInfo::RegisterTests so as to reuse some allocations, and replace stringstream with ordinary string appends. - Use std::unordered_map in UnitTestImpl::GetTestSuite and ParameterizedTestSuiteRegistry::GetTestSuitePatternHolder to spend a little memory to turn O(N) lookups into constant time lookpus. - Use range-based for loops in a few places. - Use emplace-ish methods to add to containers where appropriate. All together, these changes reduce the overall runtime of a series of 50 death tests in a single Chromium test executable by ~38% due to the fact that the registration costs are paid in every death test's child process.
