All platforms on NetBSD use a shared system call table, so use a
single XML file to describe the system calls available on each NetBSD
platform.
gdb/ChangeLog:
* syscalls/update-netbsd.sh: New file.
* syscalls/netbsd.xml: Regenerate.
* data-directory/Makefile.in: Register `netbsd.xml' in
`SYSCALLS_FILES'

# Update the netbsd.xml file.

# NetBSD uses the same list of system calls on all architectures.
|
|
# The list is defined in the sys/kern/syscalls.master file in the
|
|
# NetBSD source tree. This file is used as an input to generate
|
|
# several files that are also stored in NetBSD's source tree. This
|
|
# script parses one of those generated files (sys/sys/syscall.h)
|
|
# rather than syscalls.master as syscall.h is easier to parse.
