LLVM-MOS is an open-source fork of the LLVM C/C++ compiler, providing first-class support to the MOS Technology 65xx series of microprocessors and relatives. LLVM-MOS enables modern software development for many classic platforms.

You can play with the compiler right now on Godbolt! Here is a Commodore 64 project that shows the C compiler in action. To see a Commodore 64 calculate one hundred digits of pi, try the “Click here to simulate” link on that page.

To download and use the tool locally, see Getting started.
