Hex-Rays 生成的 C 代码添加了大量冗余代码，我无法弄清楚原因，在逆向工程过程中手动删除它们真的让我感到沮丧。

if ( v1 )
{
    v15.ObjectID = *(_DWORD *)Obj.ObjectID;
    v6 = AccessObject((Object)&v15);
    ObjectType::setTypeID(&v16, v6->Type.TypeID);
    v7 = ObjectType::getFlag(&v16, BANK);
    v4 = 0;
    if ( !v7 )
    {
      v16.TypeID = *(_DWORD *)Obj.ObjectID;
      v8 = AccessObject((Object)&v16);
      ObjectType::setTypeID((ObjectType *const )&v15, v8->Type.TypeID);
      v9 = ObjectType::getFlag((ObjectType *const )&v15, CLIP);
      v4 = 1;
      if ( !v9 )
      {
        v16.TypeID = *(_DWORD *)Obj.ObjectID;
        v10 = AccessObject((Object)&v16);
        ObjectType::setTypeID((ObjectType *const )&v15, v10->Type.TypeID);
        v11 = ObjectType::getFlag((ObjectType *const )&v15, BOTTOM);
        v4 = 2;
        if ( !v11 )
        {
          v16.TypeID = *(_DWORD *)Obj.ObjectID;
          v12 = AccessObject((Object)&v16);
          ObjectType::setTypeID((ObjectType *const )&v15, v12->Type.TypeID);
          v13 = ObjectType::getFlag((ObjectType *const )&v15, TOP);
          v4 = 3;
          if ( !v13 )
          {
            v16.TypeID = *(_DWORD *)Obj.ObjectID;
            v14 = AccessObject((Object)&v16);
            ObjectType::setTypeID((ObjectType *const )&v15, v14->Type.TypeID);
            v4 = (v15.ObjectID != 99) + 4;
          }
        }
      }
    }
  }
  else
  {
    error("GetObjectPriority: _bergebenes Objekt existiert nicht.\n");
    v4 = 0x7FFFFFFF;
  }

对 v15 堆栈变量进行了连续赋值，这完全没有意义，我怀疑这个二进制文件的实际程序员是否有这个意图。

我可以很容易地这样做：

int32_t Priority = 0;
if (Object)
{
    if (!Object->getFlag(BANK))
    {
        Priority = 1;
        if (!Object->getFlag(CLIP))
        {
            Priority = 2;
            if (!Object->getFlag(BOTTOM))
            {
                Priority = 3;
                if (!Object->getFlag(TOP))
                {
                    Priority = (Object->TypeID != 99) + 4;
                }
            }
        }
    }
}
else
{
    std::cout << "GetObjectPriority: Object is NULL." << std::endl;
    Priority = -1;
}

return Priority;

我怎么能弄乱 IDA 来阻止这种疯狂？
