V8 JavaScript Engine: Digging into the TurboFan JIT

> Interesting to see them moving away from AST-to-ASM and building an IR, which looks to be a CFG.

V8 actually has been using a compiler with a proper IR since 2010 when Crankshaft[1] was released.

It's actually a bit more relaxed than a CFG, since code is not really organized into "basic blocks" but floats around as nodes in a graph. We affectionately refer to it as a "soup of nodes".
