uLisp was too large for a small flight computer I made for a hobbyist rocket - I wanted to use it but had such little RAM I had to go down to C. I think I could have ran lisp-to-c to generate from uLisp which I’ll try on my next project.

In such contexts it is more like an Assembly with a C like macro processor than proper ANSI C anyway, and if you go the code generation route, then you would be better off using the DSL capabilites from Lisp to generate Assembly directly.
