I think you nailed this.

LLVM Is something I want to check out for some time now but never did. yacc I haven’t heard about. but its indeed what I’m getting at, why haven’t we got a single language that you can adapt to all needs.

Yes, they are there to combine several programs into the building process, and could be used for this. What I would want is programs like typescript that preprocess your code with possible changes in syntax and language specification

I’m not trying to target gcc specifically but compilers in general. I just know gcc best which is why its in my examples.
