[Vm-dev] VM Maker: VMMaker.oscog-eem.453.mcz

[Clément Bera]

Hello,

If I understand correctly now you have a working StackInterpreter with a
Spur image. I wonder, as Spur is both compatible for 32 and 64 bits, how
far are we from a Stack VM with a 64 bits image ? It shouldn't be so much
work. I'm not talking about the JIT of course.

Another question in the same direction, I saw on the Bochs website that
their simulator now also supports 64 bits. Do you think if someone try to
port Cog on 64bits he should try to use Bochs in 64 bits mode with the same
plugin as we have, or he should do another plugin for another simulator ?

Anyway I'm amazed by the speed at which you implement Spur :).
