- ootachi 15y agoYou're confusing Crankshaft with type inference. Crankshaft, which landed around Chrome 10, is an SSA-based optimization infrastructure. Type inference augments an optimization infrastructure with additional information. The two are complementary. V8 does not use type inference.
- magicalist 15y agoI don't think that's quite correct. IonMonkey also uses an SSA-based intermediate representation, and Crankshaft does generate type specialized code (as does TraceMonkey). The big thing that IonMonkey is adding is type inference through static analysis, which is a big deal for JavaScript.
- rayiner 15y agoHe's correct. This type inference is actually being added to JaegerMonkey according to the article, though IonMonkey will have it too when it's ready. Crankshaft uses type feedback, not type inference. Ie: it will monitor the types of objects to generate type-specialized code, but will not do static type inference on the code to generate type-specialized code.
