Update.
2002-07-12 Philip Blundell <philb@gnu.org>
* sysdeps/generic/backtrace.c (FIRST_FRAME_POINTER): New macro.
(__backtrace): Use it.
* sysdeps/arm/frame.h (FIRST_FRAME_POINTER): Define. [PR libc/2632]
2002-07-12 Philip Blundell <philb@gnu.org>
* sysdeps/arm/dl-machine.h (elf_machine_rel): Don't handle
R_ARM_RELATIVE if RTLD_BOOTSTRAP and HAVE_Z_COMBRELOC. Only check
for rtld map if neither RTLD_BOOTSTRAP nor HAVE_Z_COMBRELOC is defined.
(elf_machine_rela): Remove unused variable.
* sysdeps/unix/sysv/linux/arm/Makefile [subdir=elf]
(sysdep-rtld-routines, sysdep_routines, sysdep-dl-routines): Don't
define.
2002-07-12 Ulrich Drepper <drepper@redhat.com>
* iconvdata/gconv-modules: Add aliases for ISO-8859-11.
