Mihail Ionescu 8b301fbb61 Arm: Change CRC from fpu feature to archititectural extension
This patch changes the CRC extension to use the core feature bits instead
of the coproc/fpu feature bits.
CRC is not an fpu feature and it causes issues with the new fpu reset
patch (f439988037). CRC can be set using
the '.arch_extension' directive, which sets bits in the coproc bitfield. When
a '.fpu' directive is encountered, the CRC feature bit gets removed and
there is no way to set it back using '.fpu'.
With this patch, CRC will be marked in the feature core bits, which prevents
it from getting removed when setting/changing the fpu options.

gas/ChangeLog:

	* config/tc-arm.c (arm_ext_crc): New.
	(crc_ext_armv8): Remove.
	(insns): Rename crc_ext_armv8 to arm_ext_crc.
	(arm_cpus): Replace CRC_EXT_ARMV8 with ARM_EXT2_CRC.
	(armv8a_ext_table, armv8r_ext_table,
	arm_option_extension_value_table): Redefine the crc
	extension in terms of ARM_EXT2_CRC.
	* gas/testsuite/gas/arm/crc-ext.s: New.
	* gas/testsuite/gas/arm/crc-ext.d: New.

include/ChangeLog:

	* opcode/arm.h (ARM_EXT2_CRC): New extension feature
	to replace CRC_EXT_ARMV8.
	(CRC_EXT_ARMV8): Remove and mark bit as unused.
	(ARM_ARCH_V8A_CRC, ARM_ARCH_V8_1A, ARM_ARCH_V8_2A,
	ARM_ARCH_V8_3A, ARM_ARCH_V8_4A, ARM_ARCH_V8_5A,
	ARM_ARCH_V8_6A): Redefine using ARM_EXT2_CRC instead of
	CRC_EXT_ARMV8.

opcodes/ChangeLog:

	* opcodes/arm-dis.c (arm_opcodes, thumb32_opcodes):
	Change the coproc CRC conditions to use the extension
	feature set, second word, base on ARM_EXT2_CRC.

		   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.
