Joel Brobecker deede10c77 Ada subscripting of pointer to array with dynamic bounds
Consider a pointer to an array which dynamic bounds, described in
DWARF as follow:

        <1><25>: Abbrev Number: 4 (DW_TAG_array_type)
           <26>   DW_AT_name        : foo__array_type
        [...]
        <2><3b>: Abbrev Number: 5 (DW_TAG_subrange_type)
           [...]
           <40>   DW_AT_lower_bound : 5 byte block: 97 38 1c 94 4
                  (DW_OP_push_object_address; DW_OP_lit8; DW_OP_minus;
                   DW_OP_deref_size: 4)
           <46>   DW_AT_upper_bound : 5 byte block: 97 34 1c 94 4
                  (DW_OP_push_object_address; DW_OP_lit4; DW_OP_minus;
                   DW_OP_deref_size: 4)

GDB is now able to correctly print the entire array, but not one
element of the array. Eg:

    (gdb) p foo.three_ptr.all
    $1 = (1, 2, 3)
    (gdb) p foo.three_ptr.all(1)
    Cannot access memory at address 0xfffffffff4123a0c

The problem occurs because we are missing a dynamic resolution of
the variable's array type when subscripting the array. What the current
code does is "fix"-ing the array type using the GNAT encodings, but
that operation ignores any of the array's dynamic properties.

This patch fixes the issue by using ada_value_ind to dereference
the array pointer, which takes care of the array type resolution.
It also continues to "fix" arrays described using GNAT encodings,
so backwards compatibility is preserved.

gdb/ChangeLog:

        * ada-lang.c (ada_value_ptr_subscript): Remove parameter "type".
        Adjust function implementation and documentation accordingly.
        (ada_evaluate_subexp) <OP_FUNCALL>: Only assign "type" if
        NOSIDE is EVAL_AVOID_SIDE_EFFECTS.
        Update call to ada_value_ptr_subscript.

gdb/testsuite/ChangeLog:

        * gdb.dwarf2/dynarr-ptr.exp: Add subscripting tests.

README

		   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.
