* config/tc-arm.c (arm_ext_v6t2_v8m): New feature for instructions
shared between ARMv6T2 and ARMv8-M.
(move_or_literal_pool): Check mov.w/mvn and movw availability against

targetting ARMv8-M Baseline.
(non_v6t2_wide_only_insn): Add the logic for new wide-only instructions
in ARMv8-M Baseline.

(md_assemble): Use wide_insn_ok instead of non_v6t2_wide_only_insn and
adapt error message for unsupported wide instruction to ARMv8-M
Baseline.
(insns): Reorganize instructions shared by ARMv8-M Baseline and
ARMv6t2 architecture.
(arm_cpus): Set feature bit ARM_EXT2_V6T2_V8M for marvell-pj4 and
marvell-whitney cores.
(arm_archs): Define armv8-m.base architecture.
(cpu_arch_ver): Define ARM_ARCH_V8M_BASE architecture version.
(aeabi_set_public_attributes): Add logic to set Tag_CPU_arch to 17 for
ARMv8-M Mainline. Set Tag_DIV_use for ARMv8-M Baseline as well.

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.
2015-12-24 Thomas Preud'homme <thomas.preudhomme@arm.com>
* config/tc-arm.c (move_or_literal_pool): Check mov.w, mvm and movw
availability against arm_ext_v6t2 instead of checking arm_arch_t2,
fixing comments along the way.
(handle_it_state): Check arm_ext_v6t2 instead of arm_arch_t2 to
generate IT instruction.
(t1_isa_t32_only_insn): New function.
(md_assemble): Use above new function to check for invalid wide
instruction for CPU Thumb ISA and to determine what Thumb extension
bit is necessary for that instruction.
(md_apply_fix): Use arm_ext_v6t2 instead of arm_arch_t2 to decide if
branch is out of range.
