  // other ABIs do, which means that initialized function pointers must
  // reference the descriptor.  The linker must convert copy relocs of
  // pointers to functions in shared libraries into dynamic relocations,
  // because of an ordering problem with initialization of copy relocs and
  // PLT entries.  The dynamic relocation will be initialized by the dynamic
  // linker, so we must use DataRelROSection instead of ReadOnlySection.
  // For more information, see the description of ELIMINATE_COPY_RELOCS in
