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.
