Ah, no, it's still ok:

  <bb 2>:
  _1 = 327221280B;
  *_1 ={v} 97;
  _2 = 327221280B;
  *_2 ={v} 98;
  _3 = 327221280B;
  *_3 ={v} 99;
  return;

and it works for x86_64-linux.  -O2:

_Z4testv:
.LFB0:
        .cfi_startproc
        movl    $97, 327221280
        movl    $98, 327221280
        movl    $99, 327221280
        ret
