      qapi: pad GenericList value fields to 64 bits · a678e26c
      Michael Roth 提交于
      With the introduction of native list types, we now have types such as
      int64List where the 'value' field is not a pointer, but the actual
      64-bit value.
      
      On 32-bit architectures, this can lead to situations where 'next' field
      offset in GenericList does not correspond to the 'next' field in the
      types that we cast to GenericList when using the visit_next_list()
      interface, causing issues when we attempt to traverse linked list
      structures of these types.
      
      To fix this, pad the 'value' field of GenericList and other
      schema-defined/native *List types out to 64-bits.
      
      This is less memory-efficient for 32-bit architectures, but allows us to
      continue to rely on list-handling interfaces that target GenericList to
      simply visitor implementations.
      
      In the future we can improve efficiency by defaulting to using native C
      array backends to handle list of non-pointer types, which would be more
      memory efficient in itself and allow us to roll back this change.
