I have built single pass compilers that do everything in one shot without an AST. You are not going to get great error messages or optimization though.

Oh! Okay, that's interesting to me! What was the input language? I imagine it might be a little more doable if it's closer to hardware?

I don't remember that well, but I think the object oriented stuff with dynamic dispatch was hard to deal with.
