This is on my list for quite some time now and, despite having not very
much time, I can develop that, we here need bytecode profiling more than
any other improvement or enhancement to the VM.
But, what makes us reluctant is that InterpreterSimulator seems to have
collected a bit of rott. We do*not*want and have*not*much*time for the
"[development cycle via gcc] loop".
And a colleague of mine would like to do his first Squeak project and
visualize the results of profiling the bytecodes (perhaps also for the
primitives+memory routines, we have drafted a design for an easy to
implement general VM profiling implementation).
But without help from InterpreterSimulator, such a project won't fly (at
least not for us here).
