Update.
2001-04-21 Franz Sirl <Franz.Sirl-kernel@lauterbach.com> * sysdeps/unix/sysv/linux/powerpc/mmap64.c: Correct check for invalid offset. 2001-04-21 Ulrich Drepper <drepper@redhat.com> * posix/getopt.h: Treat __cplusplus like __STDC__. 2001-04-20 John S. Marvin <jsm@fc.hp.com> * sysdeps/unix/sysv/linux/hppa/clone.S: Fix clone system call entry point stub. 2001-04-20 Richard Hirst <rhirst@linuxcare.com> * elf/elf.h: Corrected R_PARISC_DIR14R (should be 6, not 5), and added R_PARISC_DPREL21L and R_PARISC_DPREL14R for modutils. * sysdeps/unix/sysv/linux/hppa/syscalls.list: Removed ptrace entry so the ptrace.c wrapper is used. 2001-04-20 Alan Modra <amodra@one.net.au> * sysdeps/hppa/dl-lookupcfg.h (_dl_function_address): Prototype. (DL_FUNCTION_ADDRESS): Define. (DL_DT_INIT_ADDRESS): Define. (DL_DT_FINI_ADDRESS): Define. * sysdeps/hppa/Versions: Add _dl_function_address. * sysdeps/hppa/dl-machine.h (ELF_MACHINE_START_ADDRESS): Define. * sysdeps/hppa/dl-symaddr.c (_dl_start_address): Rename to _dl_function_address.
