Philipp Rudo 7042632bf7 s390: Hook s390 into OSABI mechanism
Do what the title says and distinguish between 31- and 64-bit systems.
The goal is to init the OSABI as late as possible in gdbarch_init so the
OSABI has the chance to overwrite the defaults.

There are two pitfalls to be aware of:

First, the dwarf2 unwinder must be appended before the OSABI is
initialized.  Otherwise the OS could add a default unwinder which always
takes control before the dwarf unwinder even gets a chance.

Second, tdesc_use_registers has to be handled with extra care.  It sets
several gdbarch hooks, especially gdbarch_register_name, which has to be
overwritten again after the call.  Furthermore it deletes the tdesc_data
without checking.  Therefore there must not be a call to
tdesc_data_cleanup afterwards or GDB will crash with a double free.

gdb/ChangeLog:

	* s390-linux-tdep.c (osabi.h): New include.
	(s390_linux_init_abi_31, s390_linux_init_abi_64)
	(s390_linux_init_abi_any): New functions.
	(s390_gdbarch_init, _initialize_s390_tdep): Adjust.

		   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.
