Add support to the RX toolchain to restrict the use of string instructions.
bfd * elf32-rx.c (describe_flags): Report the settings of the string insn using bits. (rx_elf_merge_private_bfd_data): Handle merging of the string insn using bits. bin * readelf.c (get_machine_flags): Report the setting of the string insn using bits. gas * config/tc-rx.c (enum options): Add OPTION_DISALLOW_STRING_INSNS. (md_longopts): Add -mno-allow-string-insns. (md_parse_option): Handle -mno-allow-string-insns. (md_show_usage): Mention -mno-allow-string-insns. (rx_note_string_insn_use): New function. Produces an error message if a string insn is used when it is not allowed. * config/rx-parse.y (SCMPU): Call rx_note_string_insn_use. (SMOVU, SMOVB, SMOVF, SUNTIL, SWHILE, RMPA): Likewise. * config/rx-defs.h (rx_note_string_insn_use): Prototype. * doc/c-rx.texi: Document -mno-allow-string-insns. elf * rx.h (E_FLAG_RX_SINSNS_SET): New bit in e_flags field. (E_FLAG_RX_SINSNS_YES): Likewise. (E_FLAG_RX_SINSNS_MASK): New define.
