Joern Rennecke d4845d5762 bfd:
Reinstate bits of sh4 support that got accidentally deleted.
Add sh-dsp support.

	Modify sh_opcodes lookup table for sh-dsp / sh3-dsp.

	sh2, sh-dsp and sh3-dsp.
	Reinstate element for sh4.
	(SH2_NEXT, SH_DSP_NEXT, SH3_DSP_NEXT): New macros.

	Only include opcodes in has table that match selected architecture.
	(parse_reg): Recognize register names for sh-dsp.
	(parse_at): Recognize post-modify addressing.
	(get_operands): The leading space is now optional.
	(get_specific): Remove FDREG_N support.  Add support for sh-dsp
	arguments.  Update valid_arch.
	(build_Mytes): Add support for SDT_REG_N.
	(find_cooked_opcode): New function, broken out of md_assemble.
	(assemble_ppi, sh_elf_final_processing): New functions.
	(md_assemble): Use find_cooked_opcode and assemble_ppi.
	(md_longopts, md_parse_option): New option: -dsp.
	* config/tc-sh.h (elf_tc_final_processing): Define.
	(sh_elf_final_processing): Declare.

include/elf:

	* sh.h: (EF_SH_MACH_MASK, EF_SH_UNKNOWN, EF_SH1, EF_SH2): New macros.

	(print_insn_shx): Use info->mach to select appropriate insn set.
	Add support for sh-dsp.  Remove FD_REG_N support.
	* sh-opc.h (sh_nibble_type): Add new values for sh-dsp support.
	(sh_arg_type): Likewise.  Remove FD_REG_N.
	(sh_dsp_reg_nums): New enum.
	(arch_sh1, arch_sh2, arch_sh3, arch_sh3e, arch_sh4): New macros.
