Update.
2005-01-07 Ulrich Drepper <drepper@redhat.com> * elf/rtld.c [!DONT_USE_BOOTSTRAP_MAP] (_dl_start_final): Initialize l_relocated of rtld map. * sysdeps/powerpc/powerpc64/dl-trampoline.S: New file. * sysdeps/powerpc/powerpc64/dl-machine.h: Remove trampoline code here. Define ARCH_LA_PLTENTER and ARCH_LA_PLTEXIT. * sysdeps/generic/ldsodefs.h (struct audif_ifaces): Add ppc64 variants. * elf/tst-auditmod1.c: Add ppc64 support. * sysdeps/powerpc/powerpc64/bits/link.h: New file.
