    prog8 VM will execute if you use the 'virtual' compilaton target and use ``-emu`` to launch the VM.

 For next release
 ^^^^^^^^^^^^^^^^
-- vm: move codeGenVirtual module into virtualmachine module?
 - vm: actually translate IRProgram to vm program list again.
 - docs: modify compiler arch picture once this is done.
