We attempt to apply the technique of Tracing JIT Compilers in the context of the PyPy
project, ie, to programs that are interpreters for some dynamic languages, including Python …

The performance of many dynamic language implementations suffers from high allocation
rates and runtime type checks. This makes dynamic languages less applicable to purely …

Meta-tracing JIT compilers can be applied to a variety of different languages without
explicitly encoding language semantics into the compiler. So far, they lacked a way to give …

Polyglot programming provides software developers with a broader choice in terms of
software libraries and frameworks available for building applications. Previous research and …

Language implementation frameworks aim to provide everything that is needed to build
interpreters, simplify the process by making certain design decisions in advance, and …

Instruction set simulators (ISSs) remain an essential tool for the rapid exploration and
evaluation of instruction set extensions in both academia and industry. Due to their …

In this paper we present our experience in letting students develop RSqueak/VM, a fast
virtual machine for executing Squeak/Smalltalk, over the course of multiple introductory VM …

Object-oriented languages often use virtual machines (VMs) that provide mechanisms such
as just-in-time (JIT) compilation and garbage collection (GC). These VM components are …

Many dynamic languages are implemented using traditional interpreters because
implementing just-in-time (JIT) compilers for them is too complex. This limits their …

We report our experience in implementing SqueakJS, a bit-compatible implementation of
Squeak/Smalltalk written in pure JavaScript. SqueakJS runs entirely in the Web browser with …
