I would also like a little more details. However, this is similar to the DT_PLTGOT issue in dynamic libraries. The value chosen for %dp is arbitrary, and if we made it point into the middle of the GOT table, then you would reference the GOT using both positive and negative offsets. For example, this code: fdesc->gp = (Elf_Addr)me->module_core + me->arch.got_offset; Arbitrary chooses the module %dp to point at the start of got_offset, why not make that got_offset + <half way>.
