Details

Once we can exit from stub functions, we can implement exceptions in general. The idea here is to make try/catch/finally work for JITted code. We don't have a detailed design yet, but it seems that it could be done by calling a routine that looks at the catch/finally tables, does a bunch of unwinding, and then uses the basic bailout mechanism to return back to the point where execution should resume according to JS exception semantics.

The work for v8 takes care of try with single catch blocks. I didn't do finally blocks yet.
We're finally doing this in IonMonkey. \o/
