Tom de Vries b953e70356 [gdb/testsuite] Add missing .debug_abbrev terminator in dw2-cu-size.S
Since commit 27012aba8a "Remove Irix 6 workaround from DWARF abbrev reader"
we have:
...
(gdb) file dw2-cu-size^M
Reading symbols from dw2-cu-size...^M
DW_FORM_strp pointing outside of .debug_str section [in module dw2-cu-size]^M
(No debugging symbols found in dw2-cu-size)^M
(gdb) ptype noloc^M
No symbol table is loaded.  Use the "file" command.^M
(gdb) FAIL: gdb.dwarf2/dw2-cu-size.exp: ptype noloc
...

The problem is a missing .debug_abbrev terminator in dw2-cu-size.S, which
causes the .debug_abbrev contribution to be merged with the next:
...
 Number TAG (0x9b)
   1      DW_TAG_compile_unit    [has children]
    DW_AT_name         DW_FORM_string
    DW_AT_producer     DW_FORM_string
    DW_AT_language     DW_FORM_data1
    DW_AT value: 0     DW_FORM value: 0
   2      DW_TAG_variable    [no children]
    DW_AT_name         DW_FORM_string
    DW_AT_type         DW_FORM_ref4
    DW_AT_external     DW_FORM_flag
    DW_AT value: 0     DW_FORM value: 0
   3      DW_TAG_base_type    [no children]
    DW_AT_name         DW_FORM_string
    DW_AT_byte_size    DW_FORM_data1
    DW_AT_encoding     DW_FORM_data1
    DW_AT value: 0     DW_FORM value: 0
   4      DW_TAG_const_type    [no children]
    DW_AT_type         DW_FORM_ref_udata
    DW_AT value: 0     DW_FORM value: 0
   1      DW_TAG_compile_unit    [has children]
    DW_AT_producer     DW_FORM_strp
    DW_AT_language     DW_FORM_data1
    DW_AT_name         DW_FORM_strp
    DW_AT_comp_dir     DW_FORM_strp
    DW_AT_low_pc       DW_FORM_addr
    DW_AT_high_pc      DW_FORM_data8
    DW_AT_stmt_list    DW_FORM_sec_offset
    DW_AT value: 0     DW_FORM value: 0
...
and consequently, abbreviation code 1 no longer refers to a unique entry.

The eventually causes us to access the first attribute of this DIE:
...
 <0><124>: Abbrev Number: 1 (DW_TAG_compile_unit)
    <125>   DW_AT_name        : file1.txt
    <12f>   DW_AT_producer    : GNU C 3.3.3
    <13b>   DW_AT_language    : 1       (ANSI C)
...
which has form DW_FORM_string, using DW_FORM_strp.

Fix this by adding the missing .debug_abbrev terminator in dw2-cu-size.S.

		   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.
