Are we talking about implementing a ‘to machine code’ compiler for Guile, or about implementing an ‘AOT to machine code’? Guile already has the former – it has a JIT (bytecode -> machine code) for some systems.

For what it’s worth -- I never worked with libgccjit or with the JIT code of Guile:

I imagine a basic (POC) AOT approach for Guile would be to let it compile AOT – with the JIT implementation, except adjusted to be relocatable and to add relocation information. As far as I can tell, libgccjit does not seem to support relocations and doesn’t say anything about whether the results are position-independent or not (so not suitable fo AOT), though presumably there are ways around that given the existence of gccemacs.
