--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I added this warning in r12-4148:

g.C:3:18: warning: comparison between two arrays is deprecated in C++20
[-Warray-compare]
    3 | bool same = arr1 == arr2; // ill-formed; previously well-formed
      |             ~~~~~^~~~~~~
g.C:3:18: note: use unary ‘+’ which decays operands to pointers or ‘&arr1[0] ==
&arr2[0]’ to compare the addresses

so I can make it an error.
