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.
