Looking to write a new Bytecode back-end (Gen) for microcontroller VM

[Niels Brouwers]

Hello all,

I hope that this mailing list is the correct medium for asking this
question. If not, please forgive my intrusion.

I'm writing a Java virtual machine for microcontrollers, and since the
Java instruction set is not suitable for such platforms (32-bit stack
width is the main problem) I would like to build my own bytecode
back-end (Gen).

I've been hacking the compiler a bit today, but found it extremely
difficult to extend or change the behavior of Javac in a non-intrusive
way. I would basically like to re-use all of Javac, and simply drop in
my own bytecode generator visitor.

Before I go further with this I was wondering what the best approach
would be. Can I keep most of the Javac functionality or do I need to
write most of it from scratch?

Thanks in advance,

Niels Brouwers
