[PATCH] D128745: [c++] implements DR692, DR1395 and tentatively DR1432, about partial ordering of variadic template partial specialization or function template

[Tom Honermann via Phabricator via cfe-commits]

tahonermann added a comment.

This change appears to be responsible for the following test case now being rejected. That seems right and is consistent with the intent, but use of `-fclang-abi-compat=14` doesn't seem to restore the prior behavior. https://godbolt.org/z/ad1TPjTza

  struct map
  {
    template <typename Sequence>
    map(Sequence&& seq , void* = 0 ); // g++ prefers this one
    template <typename First, typename ...T_>
    map(First&& first, T_&&... rest);
  };
  
  int main()
  {
    int i;
    map m(i);
    return 0;
  }
