Too bad it's not open source, but will some of the generated programs be?

Also, would you mind comparing it to Csmith (https://embed.cs.utah.edu/csmith/)?

There is quite a lot of IP in the generated programs so probably not possible to share sadly.

I wasn't aware of Csmith so thanks for highlighting. My C code doesn't really test many features of the compiler so I suspect mainly of interest in seeing just how the compiler handles a really large single file.

There's also https://github.com/intel/yarpgen which I haven't used. I believe there are a couple of others...
