Hi there! With a running version of SableVM, it should be feasible to split tasks around. Using a good debugger, you should be able to look a little around and see how the beast works. In my last code, I have taken a few shortcuts (like not worrying too much about memory error conditions, etc.) to get the thing up and running, but the core structures are in place and working. I would ideally like to put my energy in the core interpreter parts. I have to implement the few missing bytecodes, add threads and GC (and make the JNI implementation safe in their presence), and patch all the shortcuts taken. If you would like to work in a particular area, please let me know. Also, for starters, there are a few relatively easy cleaning tasks available like: - putting all debugging code in functions (debug.[ch]) - making debugging output conditional (2 levels): - level 1: vm options (verbose jni/gc/class, Runtime.traceInstructions/traceMethodCalls, etc.) - level 2: static compiler conditional (#ifdef DEBUG) - verifying that all necessary "volatile" modifiers are there (and no spurious ones), and checking that prototypes are consistent with definitions on their use of modifiers Have fun!
