Thank you! I updated the fig. To tell the truth, I still cannot have
enough time playing around IR... I'll check it after JRubyKaigi2010
this weekend.
Thanks for keeping great job on IR. Frame and backtrace control during
optimizing bytecode sequence such as inlining, short-cutting must be a
heavy task for developers and runtimes if I understand correctly.
Current JRuby evaluator is doing a good job on this area, and I think we
can safely expect the similar characteristic to the new IR based one...
Anyway, I must read and check IR first.
