Wait, what's the difference between this and just using tinycc directly?
cat program.c | tcc -run -
Julia uses a model similar to this. The main advantage is that you can interact much more easily if you have a REPL running where you can do things (assign variables load data etc) and then define/try out new code on that data.
This model traces back to Lisp and how BASIC was originally designed at Dartmouth (the pure interpreter approach was a solution to fit it into 8 bit home computers).
The best tooling approach is a mix of interpreter, dynamic and ahead of time compilers, it is a pity that not all toolchains provide this.
You may be disappointed by the FAQ then https://dyne.org/cjit/faq.html (other than it really isn't an AI thing).
