--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This depends on PR 19661.

But then we still need to remove:
  <bb 2> [local count: 1073741824]:
  _1 = __atomic_load_1 (&_ZGVZ8get_basevE1d, 2);
  if (_1 == 0)
    goto <bb 4>; [33.00%]
  else
    goto <bb 3>; [67.00%]
  <bb 3> [local count: 956811341]:
  goto <bb 6>; [100.00%]

  <bb 4> [local count: 354334800]:
  _2 = __cxa_guard_acquire (&_ZGVZ8get_basevE1d);
  if (_2 != 0)
    goto <bb 5>; [33.00%]
  else
    goto <bb 3>; [67.00%]

  <bb 5> [local count: 116930483]:
  __cxa_guard_release (&_ZGVZ8get_basevE1d);


Note clang/LLVM does not remove the use of the guard here either, even though
it does remove the __cxa_atexit.
