In your case, I would do both, 1 first. You will have a kind
of a tree anyway if you generate code for a virtual
machine, an then, having both implementations, you can
check them against each other when doing some error
diagnosis.


The kind of virtual machine and it's design depends on
what your language is best suited to, I guess.


Just my opinion.
