One thing that's very cool in BBV that I'm not aware of any other JIT doing is to have type-specialized entry points for uninlinable methods. Ie if a method is not inlined then the caller calls a type specialized entry point with all the local type knowledge taken into account. In addition, the result type is propagated back out from the uninlined method to the calling function.
I couldn't help but think when I read this post last week that it's like a dynamic equivalent of CFA2; which is exciting because CFA2 is such a dramatic improvement over k-CFA for intraprocedural analysis. It's good to see how well such a simple principle about specialising type information can produce such good results. -- William Leslie Notice: Likely much of this email is, by the nature of copyright, covered under copyright law.
