	gas/
	* doc/c-arm.texi: Document .arch armv7e-m.
	* config/tc-arm.c (arm_ext_v6_dsp, arm_ext_v7m): New.
	(insns): Put Thumb versions of v5TExP instructions into
	arm_ext_v5exp also.  Move some Thumb variants from
	arm_ext_v6_notm to arm_ext_v6_dsp.
	(arm_archs): Add armv7e-m architecture.
	(aeabi_set_public_attributes): Handle -march=armv7e-m.

	gas/testsuite/
	* gas/arm/attr-march-armv7em.d: New test.
	* gas/arm/arch7em-bad.d: New test.
	* gas/arm/arch7em-bad.l: New test.
	* gas/arm/arch7em.d: New test.
	* gas/arm/arch7em.s: New test.

	include/elf/
	* arm.h (TAG_CPU_ARCH_V7E_M): Define.

	include/opcode/
	* arm.h (ARM_EXT_V6_DSP): Define.
	(ARM_AEXT_V6T2, ARM_AEXT_NOTM): Include ARM_EXT_V6_DSP.
	(ARM_AEXT_V7EM, ARM_ARCH_V7EM): Define.

	binutils/
	* readelf.c (arm_attr_tag_CPU_arch): Add v7E-M.

	bfd/
	* elf32-arm.c (using_thumb_only, arch_has_arm_nop,
	arch_has_thumb2_nop): Handle TAG_CPU_ARCH_V7E_M.
	(tag_cpu_arch_combine): Ditto. Correct MAX_TAG_CPU_ARCH test.
