There's some information in ELF documentation I've read (the
HOWTO, I think, or possible the shared library HOWTO). Not much
though -- it doesn't go into details about code generation, it
just says you must use -fPIC when building shared libraries.
The reason, I think, is that when the library is loaded into
memory its code can be shared by different programs, at
different logical addresses, so it must not require relocation.
