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. * sysdeps/i386/dl-machine.h: Likewise. * sysdeps/ia64/dl-machine.h: Likewise. * sysdeps/m68k/dl-machine.h: Likewise. * sysdeps/mips/dl-machine.h: Likewise. * sysdeps/powerpc/dl-machine.h: Likewise. * sysdeps/s390/s390-32/dl-machine.h: Likewise. * sysdeps/s390/s390-64/dl-machine.h: Likewise. * sysdeps/sh/dl-machine.h: Likewise. * sysdeps/sparc/sparc32/dl-machine.h: Likewise. * sysdeps/sparc/sparc64/dl-machine.h: Likewise.
