14. deoptimization branch by Shyohei Urabe
15. deoptimization branch by Shyohei Urabe •contains first naive implementation of JIT •used very few of JIT optimizations, but uses less memory than full-power JIT implementation •submitted at 26 Aug 2016 Reference URL: https://github.com/ruby/ruby/pull/1419
16. deoptimization branch by Shyohei Urabe •contains first naive implementation of JIT •used very few of JIT optimizations, but uses less memory than full-power JIT implementation •submitted at 26 Aug 2016 •not merged (and will not be) Reference URL: https://github.com/ruby/ruby/pull/1419
17. MJIT by Vladimir Makarov
18. Vladimir Makarov RedHat
19. MJIT by Vladimir Makarov Converted YARV to register-based instead of stack-based (smaller instructions but larger memory footprint). Built JIT on top of new VM implementation. MJIT can reach 230% performance of Ruby 2.0.0 but is pretty unstable.

21. Changed Completely
22. MJIT-JARV by Takashi Kokubun Based on Vladimir Makarov’s work, but without changing Ruby VM to register-based. Several JIT optimizations were turned off. These reverted changes made JIT slower but more stable. Reference PR: https://github.com/ruby/ruby/pull/1782 Reference ticket: https://bugs.ruby-lang.org/issues/14235 Partially merged in trunk Able to run Rails stably.
