	* config/tc-sparc.c (sparc_ip): Fix a bug which caused v9_arg_p
	instructions to loose any special insn->architecture mask.

	* config/tc-sparc.c (v9a_asr_table): Add v9b ASRs.
	(sparc_md_end, sparc_arch_types, sparc_arch,
	sparc_elf_final_processing): Handle v8plusb and v9b architectures.
	(sparc_ip): Handle siam mode operands. Support v9b ASRs (and
	request v9b architecture if they are used).

bfd/
	* elf32-sparc.c (elf32_sparc_merge_private_bfd_data,
	elf32_sparc_object_p, elf32_sparc_final_write_processing):
	Support v8plusb.
	* elf64-sparc.c (sparc64_elf_merge_private_bfd_data,
	sparc64_elf_object_p): Support v9b.
	* archures.c: Declare v8plusb and v9b machines.
	* bfd-in2.h: Ditto.
	* cpu-sparc.c: Ditto.

include/opcode/
	* sparc.h (enum sparc_opcode_arch_val): Add SPARC_OPCODE_ARCH_V9B.
	Note that '3' is used for siam operand.

opcodes/
	* sparc-dis.c (v9a_asr_reg_names): Add v9b ASRs.
	(compute_arch_mask): Add v8plusb and v9b machines.
	(print_insn_sparc): siam mode decoding, accept ASRs up to 25.
	* opcodes/sparc-opc.c: Support for Cheetah instruction set.
	(prefetch_table): Add #invalidate.
