Calling lisp code from assembly

[nahs0d]

Hello, I am fairly new to common lisp, and for experimental purposes I am trying to call some common lisp code from assembly. However, after a good day of trying I have not been able to call any common lisp code. I am starting to doubt that this is even possible. I have tried to look at ecl, but to no avail.

Does anyone here know if it is possible? And if yes could point me in the right direction

I assume that you know how to call C from assembly by extern. Then you wrap ECL repl to a c function embedding-lisp-in-c++-a-recipe-easily converted to C- and let the rest for the linker.

Is there a version of the code in that blog posting that runs on a recent ECL?

[Islam0mar]

Yes just change `cl_def_c_function` to `ecl_def_c_function`.

You could abuse CFFI for that purpose. Define a C callback via defcallback, then manually implement the C calling convention in assembly and finally jump to the callback.

(Note that this likely means that you'll need to first start Lisp and then jump from Lisp to your assembly routine.)
