Can you tell more about this part? What does this relocation include,
and to what extent the details depend on the .eln file being in ELF
format?

So when Emacs calls a Lisp function foo-bar, that call will produce a
call to 'top_level_run' function of the corresponding .eln file, and
then 'top_level_run' of that .eln will call the code produced from
'foo-bar'? How does Emacs know which .eln "provides" foo-bar?
And how would the code in the .eln know to call back into Emacs? When
you compile the native code, do you leave the symbols of Emacs
functions unresolved, and rely on the dynamic linker to resolve them?
If so, this doesn't work on Windows: you will get link errors.
Thanks.
