--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
We now say:

92416.C: In function ‘constexpr auto cmp()’:
92416.C:5:12: sorry, unimplemented: three-way comparison of vectors
    5 |   return i <=> i;
      |          ~~^~~~~
92416.C:2:1: error: invalid return type ‘auto’ of ‘constexpr’ function
‘constexpr auto cmp()’
    2 | cmp()
      | ^~~
