Andrew Burgess e06f3d6eba gdb: Support printf 'z' size modifier
The gdb format mechanism doesn't currently support the 'z' size
modifier, there are a few places in GDB where this is used.  Instead
of removing these uses lets just add support to GDB for using 'z'.

I found this issue when trying to use some of the debug output.
Before this commit:

  (gdb) set debug dwarf-line 9
  (gdb) file test
  Reading symbols from test...
  Unrecognized format specifier 'z' in printf
  (No debugging symbols found in test)
  (gdb)

After this commit:

  (gdb) set debug dwarf-line 9
  (gdb) file test
  Reading symbols from test...
  Adding dir 1: /usr/include
  Adding file 1: test.c
  Adding file 2: stdc-predef.h
  Processing actual line 3: file 1, address 0x4004a0, is_stmt 1, discrim 0
  Processing actual line 4: file 1, address 0x4004a0, is_stmt 1, discrim 0
  .... lots of debug output ...
  Processing actual line 10: file 1, address 0x4003b7, is_stmt 0, discrim 0
  (gdb)

I've added a self test to cover the integer format size modifiers,
including the 'z' modifier.

gdb/ChangeLog:

	* gdbsupport/format.c (format_pieces::format_pieces): Support
	printf 'z' size modifier.
	* gdbsupport/format.h (enum argclass): Add size_t_arg.
	* printcmd.c (ui_printf):  Handle size_t_arg.
	* ui-out.c (ui_out::vmessage): Likewise.
	* unittests/format_pieces-selftests.c (test_format_int_sizes): New
	function.
	(run_tests): Call test_format_int_sizes.

gdb/gdbserver/ChangeLog:

	* ax.c (ax_printf): Handle size_t_arg.

		   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.
