Ulrich Weigand 396d3980f5 [Cell/B.E.] Fix regression due to gdbarch_significant_addr_bit
On Cell/B.E. multi-architecture debugging we use a "merged" address space
that encodes both the main PowerPC address space and the local store address
spaces of all active SPUs.  This will always occupy 64 bits.

However, gdbarch_addr_bit is set to 32 on SPU, and may be set to 32 as well
on PowerPC.  Since the new gdbarch_significant_addr_bit defaults to the
value of gdbarch_addr_bit, this means addresses may be improperly truncated.

Work around this problem by explicitly setting gdbarch_significant_addr_bit
to 64 both for the SPU target and also for PowerPC target that support
Cell/B.E. execution.

gdb/ChangeLog:
2017-12-20  Ulrich Weigand  <uweigand@de.ibm.com>

	* spu-tdep.c (spu_gdbarch_init): Set set_gdbarch_significant_addr_bit
	to 64 bits.
	(ppc_linux_init_abi): Likewise, if Cell/B.E. is supported.

		   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.
