Overview

The purpose of the llvm-mos project is to create a first-class backend in LLVM for the MOS Technology 65xx series of microprocessors and their clones.

This will permit modern software and development methods to target common microcomputers of the 1980s, including but not limited to the Commodore 64, the Apple IIe, and the Atari 8-bit family.

The development team has established a project on Github. Acceptance tests and packaging occur via Github actions as well.

Ongoing development discussions occur on Slack, in the llvm-mos workspace.
