[Vm-dev] Currently executing bytecodes?

Hi all,

I'm stumped by the main interpreter loop: As I can't seem to get my hands on the currently executing bytecodes using the context-step simulator (same issue as desribed in http://bugs.squeak.org/view.php?id=5716), I thought I'd log them along the way directly in the VM.

However, modifying the interpreter loop to:

while (1) { printNumtoFile(currentBytecode, foo->vmLogFile); switch (currentBytecode) { .. } }

didn't work: printNumtoFile() gets executed exactly once. I've debugged this with GDB: currentBytecode gets modified from within the CASE statements and the program never gets past the switch() statement.

I wouldn't want to maintain the same code in all bytecode CASEs but I can't think of another solution at the moment.

Is there any other way to examine the currently executing bytecodes apart from the buggy ContextPart?

Thanks, André
