opcode memory layout question

[Christian Müller]

Dear Mozart people,

I've just read a little bit in Scheidhauer's thesis about the design of 
the Mozart VM. Now, I'd like to know whether some design decisions he 
made, are still up to date. Is the opcode still word sized, i.e. do you 
need one word for the instruction and one word for each argument 
(thesis, p.127)?  I know that you can compile the emulator such that it 
works for direct threaded code. Is the memory layout of the threaded 
code the same as for the switch-based emulator?

Thanks a lot for your help!

Regards,

Christian
