how to extend SableVM instructions set with macro instructions

Hi,



I'm a PhD student in France. Currently, I'm studying Java Class file compression
techniques.

To do some experiments, I would use the open source java virtual machine SableVM
(version 1.11.3).

I intend to add new instructions to JVM instructions set. I note that virtual
instructions will represent a sequence of standard instructions (bytecode
factorization technique). So I must bring some modifications to the source
code.

Can you help me to identify files that are concerned by modifications and give
me some indications to implement this extension?



Thank you in advance.
