Add assembler support for ARMv8-M Baseline
2015-12-24 Thomas Preud'homme <thomas.preudhomme@arm.com>
bfd/
(tag_cpu_arch_combine): Adjust comment in v4t_plus_v6_m with regards
to merging with ARMv8-M Baseline.
binutils/
* readelf.c (arm_attr_tag_CPU_arch): Add ARMv8-M Baseline Tag_CPU_arch
value.
gas/
* 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
arm_ext_v6t2 and arm_ext_v6t2_v8m respectively instead of checking
arm_arch_t2.
(do_t_branch): Error out for wide conditional branch instructions if
targetting ARMv8-M Baseline.
(non_v6t2_wide_only_insn): Add the logic for new wide-only instructions
in ARMv8-M Baseline.
(wide_insn_ok): New function.
(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.

include/elf/
* arm.h (TAG_CPU_ARCH_V8M_BASE): Declare.
include/opcode/
* arm.h (ARM_EXT2_V6T2_V8M): New extension bit.
(ARM_AEXT2_V8A): New architecture extension bitfield.
(ARM_AEXT2_V8_1A): Use ARM_AEXT2_V8A instead of ARM_EXT2_ATOMICS.
(ARM_AEXT_V8M_BASE): New architecture extension bitfield.
(ARM_AEXT2_V8M): Add extension bit ARM_EXT2_V6T2_V8M.
(ARM_ARCH_V6T2): Use ARM_EXT2_V6T2_V8M for the second extension
bitfield.

(ARM_ARCH_V8M_BASE): New architecture bitfield.
(ARM_ARCH_THUMB2): Include instructions shared by ARMv6t2 and ARMv8-M.
(ARM_ARCH_V7A_SEC): Use ARM_EXT2_V6T2_V8M for the second extension
bitfield and reindent.
(ARM_ARCH_V7A_MP_SEC): Likewise.
(ARM_ARCH_V7R_IDIV): Likewise.

opcodes/
* arm-dis.c (arm_opcodes): Guard movw, movt cbz, cbnz, clrex, ldrex,
ldrexb, ldrexh, strex, strexb, strexh shared by ARMv6T2 and ARMv8-M by
ARM_EXT2_V6T2_V8M instead of ARM_EXT_V6T2.
