Kwok Cheung Yeung bd286a290b Fix the gdb.dwarf2/dw2-dir-file-name.exp test on MIPS
This patch fixes the failures that occur with the
gdb.dwarf2/dw2-dir-file-name.exp test on 64-bit MIPS and compressed
MIPS ISAs (i.e. MIPS16 and microMIPS).

The failures on 64-bit occur because the generated DWARF address
information is always 32-bit, which causes the upper 32-bits of
addresses to be truncated and causes breakpoints to be set on the
wrong address if any of the upper 32-bits are non-zero.  I suspect
that other 64-bit architectures get away with it because they
place all their instructions at a VMA lower than 2^32 by default.
This patch causes 64-bit addresses to be generated if a 64-bit
target is detected.

The failures on MIPS16 and microMIPS occur because the breakpoint
address needs to have the LSB set to 1 (used to indicate that the
code is compressed). However, the function name is interpreted as
a data label, causing GDB to set breakpoints at even addresses.
This is fixed by explicitly adding a '.insn' directive (see
https://sourceware.org/binutils/docs/as/MIPS-insn.html) after the
label on MIPS only.

	* gdb.dwarf2/dw2-dir-file-name.exp (addr_len): New.
	(out_cu): Use addr_len for the size of addresses.
	(out_line): Likewise.  Size DW_LNE_set_address instruction
	according to addr_len.
	* gdb.dwarf2/dw2-dir-file-name.c (START_INSNS): New.
	(FUNC): Add START_INSNS to definition.

		   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.
