This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
Can you document this process in enough detail so that those of us with
trees/branches not yet upstream can use it to ease the process of
rebasing after this lands, please?
Replace DeviceInfo with TypeInfo, mapping:
TypeInfo::name = DeviceInfo::name
TypeInfo::parent = subclass argument to qdev_register_subclass
TypeInfo::instance_size = DeviceInfo::size
TypeInfo::class_init = DeviceInfo::class_init
Any remaining DeviceInfo members being initialized should be moved to the
class_init function as assignment to DeviceClass. Use DEVICE_CLASS() to case
the ObjectClass in the argument to DeviceClass *dc and then assign the members.
Replace qdev_register_subclass calls with type_register_static.
