	bfd/
	* elf-bfd.h (NUM_KNOWN_OBJ_ATTRIBUTES): Set to 71 to include all known
	ARM attributes in ABI 2.07.
	* elf32-arm.c (get_secondary_compatible_arch): New function.
	(set_secondary_compatible_arch): New function.
	(tag_cpu_arch_combine): New function.
	(elf32_arm_copy_one_eabi_other_attribute): Delete function.
	(elf32_arm_copy_eabi_other_attribute_list): Delete function.
	(elf32_arm_merge_eabi_attributes): Rename order_312 to order_021 to
	make it fit with order_01243.
	Add support for Tag_also_compatible_with,
	Tag_CPU_unaligned_access, Tag_T2EE_use, Tag_Virtualization_use,
	Tag_MPextension_use, Tag_nodefaults and Tag_conformance.
	Improve/tidy up support for Tag_CPU_raw_name, Tag_CPU_name,
	Tag_CPU_arch, Tag_ABI_HardFP_use, Tag_VFP_HP_extension,
	Tag_ABI_FP_denormal, Tag_ABI_PCS_GOT_use, Tag_ABI_align8_needed,
	Tag_VFP_arch and Tag_ABI_FP_16bit_format.
	Rework the way unknown attributes are handled.
	Defer errors until all attributes have been processed.

	gas/
	* config/tc-arm.c (cpu_arch): Change ARM_ARCH_V6M to 11.

	include/elf/
	* arm.h (TAG_CPU_ARCH_V6_M, TAG_CPU_ARCH_V6S_M): New defines.
	(MAX_TAG_CPU_ARCH, TAG_CPU_ARCH_V4T_PLUS_V6_M): New defines.
	(Tag_NEON_arch): Rename to Tag_Advanced_SIMD_arch to match ARM ABI
	version 2.07.
	(Tag_undefined39, Tag_nodefaults): New enum values.
	(Tag_also_compatible_with, Tag_T2EE_use): Likewise.
	(Tag_conformance, Tag_Virtualization_use): Likewise.
	(Tag_undefined69, Tag_MPextension_use): Likewise.
