The B3 JIT compiler

Original blog: https://webkit.org/blog/5852/introducing-the-b3-jit-compiler/

WebKit's FTL JIT now uses a new backend called B3 (Bare Bone Backend), which replaces LLVM as the low-level optimizer. This layer shares many principles with the Mu micro VM, most notably the role as a low-level substrate of a virtual machine.

This Wiki page will discuss the B3 JIT and its influence to the Mu micro VM.
