opcodes: * sh-dis.c (print_insn_sh): Don't disassemble fp instructions in nofpu mode. Add BFD type bfd_mach_sh4_nommu_nofpu. * sh-opc.h: Add sh4_nommu_nofpu architecture and adjust instructions accordingly. bfd: * archures.c: Add bfd_mach_sh4_nommu_nofpu. * cpu-sh.c: Ditto. * elf32-sh.c: Ditto. * bfd-in2.h: Regenerate. include/elf: * sh.h: Add EF_SH4_NOMMU_NOFPU. gas: * config/tc-sh.c (md_parse_option): Add -isa=sh4-nofpu and -isa=sh4-nommu-nofpu options. Adjust help messages accordingly. (sh_elf_final_processing): Output BFD type sh4_nofpu if that is the most general type or the user specifically requested it. (md_assemble): Add a new error message for when an instruction is understood, but is not allowed due to an -isa option.
