I mean all the pointers in the data. There are more than just 'previous' = and=20 'next'. Most Lisp objects are tagged pointers, and data contains them. > Emacs doesn't assume LSB representation when built with wide > ints. True, I should have said that the representation is always a pointer plus= a=20 constant offset, which is true even with wide ints. (It didn't used to be= true,=20 but those days are long gone.) > your proposed method is required to "serialize" the dumped data as C > code. Sure, but that's true of any dumping method. The advantage of dumping to = C code=20 is that the compiler and linker will deserialize it for you.
