   [local count: 329188777]:
  uncharge_batch (ug_26(D));
  p_size_95 = __builtin_object_size (ug_26(D), 0);
  if (p_size_95 <= 39)
goto ; [0.00%]
  else
goto ; [100.00%]

  __builtin_memset (ug_26(D), 0, 40);
  goto ; [100.00%]

   [count: 0]:
  uncharge_gather_clear.part.0 ();


uncharge_gather_clear.part.0 has

;; Function uncharge_gather_clear.part.0 (uncharge_gather_clear.part.0,
funcdef_no=6447, decl_uid=102103, cgraph_uid=6834, symbol_order=7294) (unlikely

}

I Knew I had saw this before.
