16Some Assembly Required by Aaron Patterson
Let's write a JIT for Ruby, in Ruby! We're going to learn how a JIT works from the ground up by building TenderJIT, a pure Ruby JIT compiler. First, we'll learn how Ruby's virtual machine works, then we'll learn how to plug a JIT in to the virtual machine. Finally, we'll generate machine code from our Ruby programs. By the end of the presentation we'll have a working JIT that converts Ruby code in to machine code all written in pure Ruby! But don't forget: some assembly is required!
