        # Pharo VM

This repository holds the code of the Pharo Virtual Machine.

This implementation started as a fork of [OpenSmalltalk-vm](https://github.com/OpenSmalltalk/opensmalltalk-vm).

The current project could not have been possible with all their previous work.

The current implementation presents the following core features:

- an indirect threaded bytecode compiler using GNU extensions

- a generational scavenger garbage collector: semi-space + nursery for the young generation, a mark-compact collecting for the old generation

- a space for permanent objects that need not to be scanned by the GC

- a baseline JIT compiler that

  - translates primitive operations using IR templates

  - translates bytecode methods using a simple abstract interpretation approach to reduce memory pressure (less loads/stores)

- FFI through the well-known [libFFI](https://github.com/libffi/libffi), and support for non-blocking FFI using worker threads

For more details about the whole Pharo VM project refer to our [wiki](../../wiki).
