bfd: 

Reinstate bits of sh4 support that got accidentally deleted.
Add sh-dsp support.

bfd:

	* archures.c (bfd_mach_sh2, bfd_mach_sh_dsp): New macros.
	(bfd_mach_sh3_dsp): Likewise.
	(bfd_mach_sh4): Reinstate.
	(bfd_default_scan): Recognize 7410, 7708, 7729 and 7750.
	* bfd-in2.h: Regenerate.
	* coff-sh.c (struct sh_opcode): flags is no longer short.
	(USESAS, USESAS_REG, USESR8, SETSAS, SETSAS_REG): New macros.
	(sh_opcode41, sh_opcode42): Integrate as sh_opcode41.
	(sh_opcode01, sh_opcode02, sh_opcode40): Add sh-dsp opcodes.
	(sh_opcode41, sh_opcode4, sh_opcode80): Likewise.
	(sh_opcodes): No longer const.
	(sh_dsp_opcodef0, sh_dsp_opcodef): New arrays.
	(sh_insn_uses_reg): Check for USESAS and USESR8.
	(sh_insn_sets_reg, sh_insns_conflict): Check for SETSAS.
	(_bfd_sh_align_load_span): Return early for SH4.
	Modify sh_opcodes lookup table for sh-dsp / sh3-dsp.
	Take into account that field b of a parallel processing insn
	could be mistaken for a separate insn.
	* cpu-sh.c (arch_info_struct): New array elements for
	sh2, sh-dsp and sh3-dsp.
	Reinstate element for sh4.
	(SH2_NEXT, SH_DSP_NEXT, SH3_DSP_NEXT): New macros.
	(SH4_NEXT): Reinstate.
	(SH3_NEXT, SH3E_NEXT): Adjust.
	* elf-bfd.h (_sh_elf_set_mach_from_flags): Declare.
	* elf32-sh.c (sh_elf_set_private_flags): New function.

	(sh_elf_merge_private_data): New function.
	(elf_backend_object_p, bfd_elf32_bfd_set_private_bfd_flags): Define.
	(bfd_elf32_bfd_copy_private_bfd_data): Define.
	(bfd_elf32_bfd_merge_private_bfd_data): Change to
	sh_elf_merge_private_data.

gas:

	* config/tc-sh.c ("elf/sh.h"): Include.
	(sh_dsp, valid_arch, reg_x, reg_y, reg_efg): New static variables.
	(md.begin): Initialize target_arch.
	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.
