Anton Kolesov e1e94c4994 [ARC] Fix handling of cpu=... disassembler option value
There is a bug in handling of cpu=... disassembler option in case there are
other options after it, for example, `cpu=EM,dsp'.  In this case `EM,dsp' is
treated as an option value, and strcasecmp reports is as non-equal to "EM".
This is fixed by using disassembler_options_cmp function, which compares string
treating `,' the same way as `\0'.

This function also solves a problem with option order in parse_option.
Previously, if several option had same prefix (e.g. fpud, fpuda), then the
longer one should have been compared first, otherwise when longer option is
passed it would be treated as a short one, because

  CONST_STRNEQ ("fpud", "fpuda")

would be true.  The order of options was correct for ARC, so there were no
bugs per se, but with disassembler_option_cmp there is no risk of such a bug
being introduced in the future.

opcodes/ChangeLog:

yyyy-mm-dd  Anton Kolesov  <Anton.Kolesov@synopsys.com>

	* arc-dis.c (parse_option): Use disassembler_options_cmp to compare
	disassembler option strings.
	(parse_cpu_option): Likewise.

binutils/ChangeLog

yyyy-mm-dd  Anton Kolesov  <Anton.Kolesov@synopsys.com>

	* testsuite/binutils-all/arc/double_store.s: New file.
	* testsuite/binutils-all/arc/objdump.exp: Tests for disassembler
	options.
	(do_objfile): New function.
	(check_assembly): Likewise.

		   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.
