Pedro Alves 40c31709c6 Fix PR gdb/20413 - x32: linux_ptrace_test_ret_to_nx: Cannot PTRACE_PEEKUSER
An x32 gdb always issues this warning:

 (gdb) start
 Temporary breakpoint 1 at 0x4043e9: file foo.c, line 25.
 Starting program: a.out
 warning: linux_ptrace_test_ret_to_nx: Cannot PTRACE_PEEKUSER: Input/output error

 Temporary breakpoint 1, main (argc=1, argv=0xffffd544) at foo.c:25
 25      {
 (gdb)

As described in Linux commit 55283e253771 (x32: Add ptrace for x32):

    [...] PTRACE_PEEKUSR and PTRACE_POKEUSR are only allowed to access
    segment and debug registers. [...]

The fix is to use PTRACE_GETREGS instead.

gdb/ChangeLog:
2016-07-26  Pedro Alves  <palves@redhat.com>

	* nat/linux-ptrace.c: Include "gregset.h".
	(linux_ptrace_test_ret_to_nx): Use PTRACE_GETREGS instead of
	PTRACE_PEEKUSER.

		   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.
