Thomas Preud'homme 4070243b5c [ARM] Fix Coprocessor instructions availability
A few coprocessor instructions introduced in ARMv2 are currently
accepted by GAS when targeting ARMv1 due to a typo in the code. This
patch fixes the issue and introduce a more fine grained testing for
coprocessor instructions availability. Coprocessor instructions are
grouped as follows:

* ARM coprocessor instructions introduced in ARMv2
  Includes: ldc, stc, mcr, mrc, cdp, ldcl, stcl
  Guarded by: ARM_EXT_V2
  Tests: copro-arm_v2plus-arm_v*.d

* ARM coprocessor instructions introduced in ARMv5
  Includes: ldc2, ldc2l, stc2, stc2l, cdp2, mcr2, mrc2
  Guarded by: ARM_EXT_V5
  Tests: copro-arm_v5plus-arm_v*.d

* ARM coprocessor instructions introduced in ARMv5TE
  Includes: mcrr, mrrc
  Guarded by: ARM_EXT_V5E
  Tests: copro-arm_v5teplus-arm_v*.d

* ARM coprocessor instructions introduced in ARMv6
  Includes: mcrr2, mrrc2
  Guarded by: ARM_EXT_V6
  Tests: copro-arm_v6plus-arm_v*.d

* Thumb coprocessor instructions introduced in ARMv6T2
  Includes: ldc, ldcl, stc, stcl, mcr, mrc, mcrr, mrrc, cdp, ldc2,
  ldc2l, stc2, stc2l, cdp2, mcr2, mrc2, mcrr2, mrrc2
  Guarded by: ARM_EXT_V6T2
  Tests: copro-thumb_v6t2plus-thumb_v*.d

For each of these groups, at least 2 tests are performed:
* instructions are not available in earlier architecture
* instructions are available in architecture where they were introduced
More tests need to be performed when instructions in a group span
several assembly files.

Note that an instruction in the original coprocessor testcase is
changed to unified syntax to allow the testcase to be assembled for ARM
and Thumb state. Correct processing of legacy syntax is covered in other
testcases.

		   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.
