Andreas Arnez bf2d68ab8c S390: Add vector register support to gdbserver
On S/390 targets with vector registers, enable gdbserver to advertise
and handle the feature "org.gnu.gdb.s390.vx".

gdb/gdbserver/ChangeLog:

	* Makefile.in (s390-vx-linux64.c, s390-tevx-linux64.c)
	(s390x-vx-linux64.c, s390x-tevx-linux64.c): New rules.
	(clean): Add "rm -f" for above C files.
	* configure.srv (srv_regobj): Add s390-vx-linux64.o,
	s390-tevx-linux64.o, s390x-vx-linux64.o, and s390x-tevx-linux64.o.
	(srv_xmlfiles): Add s390-vx-linux64.xml, s390-tevx-linux64.xml,
	s390x-vx-linux64.xml, s390x-tevx-linux64.xml, and s390-vx.xml.
	* linux-s390-low.c (HWCAP_S390_VX): New macro.
	(init_registers_s390_vx_linux64, init_registers_s390_tevx_linux64)
	(init_registers_s390x_vx_linux64)
	(init_registers_s390x_tevx_linux64)
	(tdesc_s390_vx_linux64, tdesc_s390_tevx_linux64)
	(tdesc_s390x_vx_linux64, tdesc_s390x_tevx_linux64): New extern
	declarations.
	(s390_fill_vxrs_low, s390_store_vxrs_low, s390_fill_vxrs_high)
	(s390_store_vxrs_high): New functions.
	(s390_regsets): Add entries for NT_S390_VXRS_LOW and
	NT_S390_VXRS_HIGH.
	(s390_arch_setup): Add logic for selecting one of the new target
	descriptions.  Activate the new vector regsets if applicable.
	(initialize_low_arch): Also invoke init_registers_s390_vx_linux64,
	init_registers_s390_tevx_linux64, init_registers_s390x_vx_linux64,
	and init_registers_s390x_tevx_linux64.

		   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.
