v8: a Tale of Two Compilers

Ever wanted to take a peek under the hood of [v8, Google's Javascript virtual machine](http://code.google.com/p/v8/), without having to check out the code and poke around? [Here is a nice post](http://wingolog.org/archives/2011/07/05/v8-a-tale-of-two-compilers) that gives a look at what's going on behind the scenes:

> V8 compiles all JavaScript to native code. V8 has two compilers: one that runs fast and produces generic code, and one that doesn't run as fast but does try to produce optimized code.

> The quick-and-simple compiler is known internally as the "full-codegen" compiler. It takes as its input the abstract syntax tree (AST) of a function, walks over the nodes in the AST, and emits calls to a macroassembler directly.
