Inside Mozilla's New JavaScript JIT Compiler 97

An anonymous reader writes "IonMonkey is the name of Mozilla's new JavaScript JIT compiler, which aims to enable many new optimizations in the SpiderMonkey JavaScript engine. InfoQ had a small Q&A with Lead Developer David Anderson, about this new development that could bring significant improvements in products that use the SpiderMonkey engine like Firefox, Thunderbird, Adobe Acrobat, MongoDB and more. This new JIT infrastructure, will feature SSA compiler intermediate representations which will facilitate advanced optimizations such as type specialization, function inlining, linear-scan register allocation, dead-code elimination, and loop-invariant code motion."
