Tiezhu Yang a08dc2aa00 gdb: syscalls: Add loongarch-linux.xml.in
There is no syscall.tbl for LoongArch because it uses generic syscalls,
so it can not generate loongarch-linux.xml.in automatically through the
script update-linux-from-src.sh, make use of the script update-linux.sh
to generate loongarch-linux.xml.in.

Like this:

  $ git clone https://sourceware.org/git/binutils-gdb.git gdb.git
  $ cd gdb.git/gdb/syscalls/
  $ touch loongarch-linux.xml.in
  $ ./update-linux.sh loongarch-linux.xml.in

Note that the system header file /usr/include/asm-generic/unistd.h
may be different with the latest upstream Linux kernel uapi header
file include/uapi/asm-generic/unistd.h, it is better to copy the
upstream header file into the system header file when generating
loongarch-linux.xml.in.

There exist some __NR3264_ prefixed syscall numbers, replace them
with digital numbers according to /usr/include/asm-generic/unistd.h
and sort them by syscall number manually, maybe we can modify the
script to do it automatically in the future.

  <syscall name="fcntl" number="__NR3264_fcntl"/>
  <syscall name="statfs" number="__NR3264_statfs"/>
  <syscall name="fstatfs" number="__NR3264_fstatfs"/>
  <syscall name="truncate" number="__NR3264_truncate"/>
  <syscall name="ftruncate" number="__NR3264_ftruncate"/>
  <syscall name="lseek" number="__NR3264_lseek"/>
  <syscall name="sendfile" number="__NR3264_sendfile"/>
  <syscall name="mmap" number="__NR3264_mmap"/>
  <syscall name="fadvise64" number="__NR3264_fadvise64"/>

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
