Update.
2000-06-19 Ulrich Drepper <drepper@redhat.com>
* elf/sprof.c (print_version): Update year.
* elf/sprof.c (load_shobj): Don't always add load address to dynamic
table entry values. Use D_PTR.
* elf/dl-reloc.c (_dl_relocate_object): Don't start profiling weird
binaries without PLT. Patches by James Mathiesen <james@curl.com>.
