Visual C++ optimization options - how to improve the code output?

Are there any options (other than /O2) to improve the Visual C++ code output? The MSDN documentation is quite bad in this regard. Note that I'm not asking about project-wide settings (link-time optimization, etc...). I'm only interested in this particular example.

The fairly simple C++11 code looks like this:

#include <vector>
int main() {
    std::vector<int> v = {1, 2, 3, 4};
    int sum = 0;
    for(int i = 0; i < v.size(); i++) {
        sum += v[i];
    }
    return sum;
}

Clang's output with libc++ is quite compact:

main: # @main
  mov eax, 10
  ret

Visual C++ output, on the other hand, is a multi-page mess. Am I missing something here or is VS really this bad?
