Joel Brobecker b26daff97c fix printing of DWARF fixed-point type objects with format modifier
Consider a fixed-point type such the scaling factor is 1/16,
as the following Ada code snippet would create:

      type FP1_Type is delta 0.1 range -1.0 .. +1.0;
      FP1_Var : FP1_Type := 0.25;

Printing the value of this variable with a format modifier yields
the wrong value. E.g.:

    (gdb) p /x fp1_var
    $6 = 0x4

Since the real value is 0.25, we therefore expected...

    (gdb) p /x fp1_var
    $6 = 0x0

What happens, in this case, is that the value being printed is
actually the "raw" value of our object, before the scaling factor
gets applied.

This commit fixes the issue by using approach as for float values,
where we convert the value into an integer value, prior to printing,
knowing that the conversion takes the scaling factor into account.

gdb/ChangeLog:

        * printcmd.c (print_scalar_formatted): Add fixed-point type
        handling when options->format is set.

gdb/testsuite/ChangeLog:

        * gdb.dwarf2/dw2-fixed-point.exp: Add "print /x" tests.

		   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.
