I already send this email to the vm-dev list, yet found that squeak-dev might be interested in this as well. I have built a debugger that allows us to debug multiple language levels within the same debugger. Here is a demo of my current work,
what do you think about that?
In this video-walkthrough, I am in an application and debugging the issue that minSmallInt // -1 does return minSmallInt. I step through the application, AST, and Smalltalk Bytecode. On the lower levels, I have a feature to debug the translators
and finally fix the bug in the JIT-Compiler right in the debugger. This is going to be the core of my master thesis. I will speak about it on OOPS at SAC in April.
