[libc++] Benchmark std::regex implemenations between libc++ and libstdc++

Hello.

Have anybody any benchmark results of std::regex between libc++ and libstdc++ implementations? Has libc++ any automatic benchmarks for the std::regex implementation?

Best regards,

I don’t know of any libc++ benchmarks for std::regex. Looking at https://github.com/llvm-mirror/libcxx/tree/master/benchmarks, there doesn’t seem to be any.

The WebKit team was working on a regex benchmark:

I expect browsers to perform much better than C++ implementations because they’ll JIT the regular expressions. It would be neat to use the same benchmarks to see the difference.
