Keven Boell 3f2f83ddcb fort_dyn_array: add basic fortran dyn array support
Fortran provide types whose values may be dynamically allocated
or associated with a variable under explicit program control.
The purpose of this commit is:

  * to read allocated/associated DWARF tags and store them in
    the dynamic property list of main_type.

  * enable GDB to print the value of a dynamic array in Fortran
    in case the type is allocated or associated (pointer to
    dynamic array).

Examples:
    (gdb) p vla_not_allocated
    $1 = <not allocated>

    (gdb) p vla_allocated
    $1 = (1, 2, 3)

    (gdb) p vla_ptr_not_associated
    $1 = <not associated>

    (gdb) p vla_ptr_associated
    $1 = (1, 2, 3)

Add basic test coverage for most dynamic array use-cases in Fortran.
The commit contains the following tests:
  * Ensure that values of Fortran dynamic arrays
    can be evaluated correctly in various ways and states.
  * Ensure that Fortran primitives can be evaluated
    correctly when used as a dynamic array.
  * Dynamic arrays passed to subroutines and handled
    in different ways inside the routine.
  * Ensure that the ptype of dynamic arrays in
    Fortran can be printed in GDB correctly.
  * Ensure that dynamic arrays in different states
    (allocated/associated) can be evaluated.
  * Dynamic arrays passed to functions and returned from
    functions.
  * History values of dynamic arrays can be accessed and
    printed again with the correct values.
  * Dynamic array evaluations using MI protocol.
  * Sizeof output of dynamic arrays in various states.

The patch was tested using the test suite on Ubuntu 12.04 64bit.

		   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.
