Update.
2001-08-24 Ulrich Drepper <drepper@redhat.com>
* elf/do-rel.h (elf_dynamic_do_rel): If not relocating lazily, don't
call elf_machine_rel for the last DT_RELCOUNT relocations but instead
elf_machine_rel_relative.
* sysdeps/alpha/dl-machine.h: Define elf_machine_rel_relative.
Minor optimizations.
* sysdeps/arm/dl-machine.h: Likewise.
* sysdeps/cris/dl-machine.h: Likewise.
* sysdeps/hppa/dl-machine.h: Likewise.
