Yes, you can call an OCaml function from assembler using the same method
as from C, that is through caml_callback* functions (see Section 18.7.1
in the OCaml manual). However, dealing with the GC properly in assembler
is tricky: you'll have to reproduce the behavior of the CAMLlocal and
CAMLparam macros.
