[boost] [gsoc17] Project1: Static map: Can I implement the competency test in g++-7?

3 Mar 2017

      Hi,

I'm Zheng Luo, a third-year undergraduate from Shanghai Jiaotong
University who have special interest in C++ programming(especially for
templates). This is my second year of applying Google Summer of Code and
I'm willing to contribute to Static Map project mentioned on SoC2017
page. Previously I worked for a company as a C++ intern for months on
Chromium-related projects where I gained some experience about C++ in
industry.

And my question is, am I allowed to implement the competency test of
static_map in g++-7? I have just implemented my own version of
static_map which supports the following operations:

constexpr StaticMap m(make_pair(2, "abc"),
make_pair(4, "def"), make_pair(6, "ghi"));

    if (!m[4])
      abort();
    const char *foo = m[2];
    return 0;

which is compiled into assembly as:

main:
        xorl    %eax, %eax
        ret

under g++-7 with -std=c++1z -O3

So I was wondering did I pass the test?

Thanks,
