Inspecting Just-in-Time Compiled JavaScript – Attack & Defense
The security implications of Just-in-Time (JIT) Compilers in browsers have been getting attention for the past decade and the references to more recent resources is too great to enumerate. While it’s not the only class of flaw in a browser, it is a common one; and diving deeply into it has a higher barrier to entry than, say, UXSS injection in the UI. This post is about lowering that barrier to en

Introducing the B3 JIT Compiler
As of r195562, WebKit’s FTL JIT (Faster Than Light Just In Time compiler) now uses a new backend on OS X. The Bare Bones Backend, or B3 for short, replaces LLVM as the low-level optimizer in the FTL JIT. While LLVM is an excellent optimizer, it isn’t specifically designed for the optimization challenges of dynamic languages like JavaScript. We felt that we could get a bigger speed-up if we combine
