	* config/tc-arm.c (arm_ext_barrier, arm_ext_msr): New.
	(arm_ext_v7m): Rename...
	(arm_ext_m): ... to this.  Include v6-M.
	(do_t_add_sub): Allow narrow low-reg non flag setting adds.
	(do_t_mrs, do_t_msr, aeabi_set_public_attributes): Use arm_ext_m.
	(md_assemble): Allow wide msr instructions.
	(insns): Add classifications for v6-m instructions.
	(arm_cpu_option_table): Add cortex-m1.
	(arm_arch_option_table): Add armv6-m.
	(cpu_arch): Add ARM_ARCH_V6M.  Fix numbering of other v6 variants.

	gas/testsuite/
	* gas/arm/archv6m.d: New test.
	* gas/arm/archv6m.s: New test.
	* gas/arm/t16-bad.s: Test low register non flag setting add.
	* gas/arm/t16-bad.l: Update expected output.
