Tom de Vries 714534e1b8 [gdb/testsuite] Fix .debug_aranges in gdb.dlang/watch-loc.c
While investigating PR25862 (an assertion failure with target board
cc-with-debug-names), I noticed that the .debug_aranges section in
gdb.dlang/watch-loc.c contains a hardcoded 0x1000:
...
"      .4byte  _Dmain \n"      // Address
"      .4byte  0x1000 \n"      // Length
...

Fix this by using the actual length of _Dmain, along the lines of how that
is done in gdb.mi/dw2-ref-missing-frame-func.c:
...
"      .4byte  _Dmain_end - _Dmain \n" // Length
...
such that the .debug_aranges entry:
...
    Address    Length
    004004a7 0000000b
    00000000 00000000
...
matches the addresses found in the corresponding CU:
...
 <2><fd>: Abbrev Number: 6 (DW_TAG_subprogram)
    <fe>   DW_AT_name        : _Dmain
    <105>   DW_AT_low_pc      : 0x4004a7
    <10d>   DW_AT_high_pc     : 0x4004b2
...

With this fix the assertion failure is no longer triggered for
gdb.dlang/watch-loc.exp.

Tested on x86_64-linux.

		   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.
