For fun, I wrote a c compiler (non-optimizing) in Java targeting modern C (C23) using claude. I developed a c shell similar to jshell in java. The compiler also bundles a built in an assembler for x86. A linker is planned for end-to-end compilation. There is still a lot of work in progress but I wanted to share the project early for feedback. I spent around $400 in AI credits so far and it took over a week on and off of working on it.

I drive the architecture of the compiler and verify the AI implementation with a large test suite.

It can compile and run lua (all test passing) and curl (partially).

Cheers!
