Tom de Vries 37cc0caeca [gdb/exp] Interpret size of vla with unknown size as <optimized out>
At -O3 -g -gstrict-dwarf, gcc generates for an optimized out vla 'a' a
DW_TAG_variable with type DW_TAG_array_type containing one
DW_TAG_subrange_type, but without DW_AT_upper_bound or DW_AT_count, which
makes the upper bound value 'unknown':
...
	.uleb128 0x15   # (DIE (0x161) DW_TAG_variable)
        .long   0xec    # DW_AT_abstract_origin
        .long   0x170   # DW_AT_type
	...
        .uleb128 0xa    # (DIE (0x170) DW_TAG_array_type)
        .long   0x110   # DW_AT_type
        .long   0x17f   # DW_AT_sibling
        .uleb128 0x17   # (DIE (0x179) DW_TAG_subrange_type)
        .long   0xc6    # DW_AT_type
        .byte   0       # end of children of DIE 0x170
...

But gdb prints '0' for the size of 'a':
...
/gdb ./vla-1.exe -batch -ex "b f1" -ex "run" -ex "p sizeof(a)"
Breakpoint 1 at 0x4004c0: f1. (2 locations)

Breakpoint 1, f1 (i=<optimized out>) at vla-1.c:18
18      }
$1 = 0
...
while <optimized out> would be more appropriate.

This patch fixes that in evaluate_subexp_for_sizeof.

Build and reg-tested on x86_64-linux.

2018-07-28  Tom de Vries  <tdevries@suse.de>

	* eval.c (evaluate_subexp_for_sizeof): Interpret size of dynamic type
	with undefined upper bound as <optimized out>.

	* gdb.base/vla-optimized-out-o3-strict.exp: New file.

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.
