Where is the ELF moving information located?

Quoting “linkers and loaders” in the “Loaders” section

"moving the load time is much easier than moving the link time, because the whole program moves as a unit. [...] After reading the program in memory, the loader copes moving the elements in the object file and correcting the memory location indicated by the points"

Perhaps I misunderstood this point, and this is only in some architectures, but my question is: where in the ELF format it is indicated which elements should be moved during loading? How can I find this list?
