--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
-mstore-max=3D128 -mmove-max=3D128 avoids it and we inline the memcpy as

      D.5177 =3D MEM <_BitInt(512)> [(char * {ref-all})&x];
      MEM <_BitInt(512)> [(char * {ref-all})digits.0] =3D D.5177;

using a _BitInt(512) temporary instead.=
