Thomas Preud'homme 4ed7ed8db2 Add assembler support for ARMv8-M Mainline
2015-12-24  Thomas Preud'homme  <thomas.preudhomme@arm.com>

bfd/
    (tag_cpu_arch_combine): Adjust v4t_plus_v6_m and comb array to account
    for new TAG_CPU_ARCH_V4T_PLUS_V6_M value.  Deal with NULL values in
    comb array.

binutils/
    * readelf.c (arm_attr_tag_CPU_arch): Add ARMv8-M Mainline Tag_CPU_arch
    value.
    (arm_attr_tag_THUMB_ISA_use): Add ARMv8-M Mainline Tag_THUMB_ISA_use
    value.

gas/
    * config/tc-arm.c (arm_ext_m): Include ARMv8-M.
    (arm_ext_v8m): New feature for ARMv8-M.
    (arm_ext_atomics): New feature for ARMv8 atomics.
    (do_tt): New encoding function for TT* instructions.
    (insns): Add new entries for ARMv8-M specific instructions and
    reorganize the ones shared by ARMv8-M Mainline and ARMv8-A.
    (arm_archs): Define armv8-m.main architecture.
    (cpu_arch_ver): Define ARM_ARCH_V8M_MAIN architecture version and
    clarify the ordering rule.
    (aeabi_set_public_attributes): Use TAG_CPU_ARCH_* macro to refer to
    Tag_CPU_arch values for ARMv7e-M detection.  Add logic to keep setting
    Tag_CPU_arch to ARMv8-A for -march=all.  Also set Tag_CPU_arch_profile
    to 'A' if extension bit for atomic instructions is set, unless it is
    ARMv8-M.  Set Tag_THUMB_ISA_use to 3 for ARMv8-M.  Set Tag_DIV_use to 0
    for ARMv8-M Mainline.

		   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.
