-/* We pass reloc_addr as a pointer to void, as opposed to a pointer to
- ElfW(Addr), because not all architectures can assume that the
- relocated address is properly aligned, whereas the compiler is
- entitled to assume that a pointer to a type is properly aligned for
- the type. Even if we cast the pointer back to some other type with
- less strict alignment requirements, the compiler might still
- remember that the pointer was originally more aligned, thereby
- optimizing away alignment tests or using word instructions for
- copying memory, breaking the very code written to handle the
- unaligned cases. */
