2014-10-31  Andrew Pinski  <apinski@cavium.com>
            Naveen H.S  <Naveen.Hurugalawadi@caviumnetworks.com>

	* gas/mips/mips.exp: Add support for Octeon3 architecture.
	Also add in support for running Octeon3 tests.
	* gas/mips/octeon3.d: New test.
	* gas/mips/octeon3.s: New test source.

opcodes:
2014-10-31  Andrew Pinski  <apinski@cavium.com>
            Naveen H.S  <Naveen.Hurugalawadi@caviumnetworks.com>

	* mips-dis.c (mips_arch_choices): Add octeon3.
	* mips-opc.c (IOCT): Include INSN_OCTEON3.
	(IOCT2): Likewise.

	tlbinv, tlbinvf, tlbgr, tlbgwi, tlbginv, tlbginvf, tlbgwr, tlbgp, tlti
	IVIRT instructions.
	Extend mtm0, mtm1, mtm2, mtp0, mtp1, mtp2 instructions to take another
	operand for IOCT3.

	* archures.c: Add octeon3 for mips target.
	* bfd-in2.h: Regenerate.
	* bfd/cpu-mips.c: Define I_mipsocteon3.
	nfo_struct): Add octeon3 support.
	* bfd/elfxx-mips.c: (_bfd_elf_mips_mach): Add support for
	octeon3.
	(mips_set_isa_flags): Add support for octeon3.
	(bfd_mips_isa_ext): Add bfd_mach_mips_octeon3.
	(mips_mach_extensions): Make bfd_mach_mips_octeon3 an
	extension of bfd_mach_mips_octeon2.
