Update.

1999-04-12  Philip Blundell  <philb@gnu.org>

	* elf/elf.h: Update ARM definitions to match current gas2.

	* sysdeps/arm/bits/endian.h: Support big endian operation.

	* sysdeps/unix/sysv/linux/arm/ioperm.c (_outw, _outb, _outl):
	Don't bother range checking the port number.

	* sysdeps/unix/sysv/linux/arm/vfork.S: New file.

	* sysdeps/unix/sysv/linux/arm/sysdep.h (INLINE_SYSCALL): Include
	the syscall name in assembler output for ease of debugging.

	* sysdeps/unix/sysv/linux/arm/sigaction.c: Don't rely on undefined
	compiler behaviour.
	* sysdeps/unix/sysv/linux/arm/sigrestorer.S: New file.
	* sysdeps/unix/sysv/linux/arm/Makefile [$(subdir) = signal]
	(sysdep_routines): Add sigrestorer.

	* string/tester.c (test_strcpy): Add new tests for unaligned
	arguments.
	* sysdeps/arm/bits/string.h: Delete inline implementations of
	strcpy and stpcpy.
