A family of virtual machines that supports Smalltalk and other languages of the Smalltalk family, including the standard VM for Squeak, Pharo and Newspeak. Just-in-time compilation, stack-to-register mapping, and aggressive in-line message caching yield efficiency in executing Smalltalk byte code. Being a fork of VMMaker, OpenSmalltalk VMs provide safe incremental development of JIT VMs.
An experimental virtual machine written in RPython and based on PyPy’s meta-tracing JIT Compiler infrastructure.
