The differences are not quite that big. Majority of code is shared.
On the other hand, if completely split, the code would be a bit more
Is the code in question really updated so seldomly ?

How would inlines help here ?
Like you'd suggest to put the code in header file and pull in via
inline ? That would not work, I need to put pointer of the function
to struct emul.
