Walfred Tedeschi f92b06daf9 Fix display of structures/bitfields in register description.
Add support for displaying structures and bitfields for registers when
executing "maint print c-tdesc". This command is also used when
converting the xml target description file into c file.

Example of the behaviour is given below reporting a snipet of the xml file
and a snippet of the c code generated.

XML file contains:
...
    <union id="vecint">
      <field name="v4" type="v4int8"/>
      <field name="v2" type="v2int16"/>
    </union>

    <struct id="struct1">
      <field name="v4" type="v4int8"/>
      <field name="v2" type="v2int16"/>
    </struct>

    <struct id="struct2" size="8">
      <field name="f1" start="0" end="34"/>
      <field name="f2" start="63" end="63"/>
    </struct>
...

Setting this xml file as target description file and
issuing the maintenance print c-tdesc the following output
is obtained:

  feature = tdesc_create_feature (result, "extra");
  field_type = tdesc_named_type (feature, "int8");
  tdesc_create_vector (feature, "v4int8", field_type, 4);

  field_type = tdesc_named_type (feature, "int16");
  tdesc_create_vector (feature, "v2int16", field_type, 2);

  type = tdesc_create_union (feature, "vecint");
  field_type = tdesc_named_type (feature, "v4int8");
  tdesc_add_field (type, "v4", field_type);
  field_type = tdesc_named_type (feature, "v2int16");
  tdesc_add_field (type, "v2", field_type);

C output is not supported type "struct1".

This is finally the issue.

        * target-descriptions.c (maint_print_c_tdesc_cmd):
        Add case to parse structures as register types and
        bitfields.

		   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.
