--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
With -mtune=sapphirerapids we get:
<bb 2> [local count: 1073741824]:
MEM <unsigned long> [(union *)lock_2(D)] = 0;
MEM <unsigned long> [(union *)lock_2(D) + 8B] = 0;
MEM <unsigned long> [(union *)lock_2(D) + 16B] = 1;
MEM <vector(2) long unsigned int> [(union *)lock_2(D) + 24B] = { 0, 0 };
Which is because we don't combine "memset"s into large ones yet.
Which is PR 49872.
