Could you please sketch how this is accomplished in emacs, given its
lisp base?  I.e. as one initializes the lisp when building emacs, does
one not create function objects containing pointers/function addresses
which are then dumped in the unexec?  Or are all lisp function objects
statically defined in C source files as explicitly initialized
structures? 

Take care,
