Determining the -std=xxx option possibilities for C++ in clang releases

Is there any way, beyond pure experimentation, to determine the possible -std=xxx possibilities for C++ compilation in past and current clang releases ?

I can find no documentation, aside from C language possibilities for the -std option, in either the documentation or the clang --help command, for any given clang release which tells me what the possible -std possibilities are for C++ compilation. I am interested in the possibilities for clang 3.4 up to the present source.

Wouldn’t this be derivable from http://clang.llvm.org/cxx_status.html ?

That's helpful. I guess I can try -std=c++11, -std=c++14 or -std=c++1z on all relevant compiler versions and see if that compiler version accepts the option.
