        * config/tc-nds32.c (struct nds32_relocs_pattern): Add `insn' field.
        (struct nds32_hint_map): Add `option_list' field.
        (struct suffix_name, suffix_table): Remove the unused `pic' field.
        (do_pseudo_b, do_pseudo_bal): Remove the suffix checking.
        (do_pseudo_la_internal, do_pseudo_pushpopm): Indent.

        (CLEAN_REG, GET_OPCODE): New macros.
        (struct relax_hint_id): New.
        (nds32_relax_hint): For .relax_hint directive, we can use `begin'
        and `end' to mark the relax pattern without giving exactly id number.
        (nds32_elf_append_relax_relocs): Handle the case that the .relax_hint
        directives are attached to pseudo instruction.
        (nds32_elf_save_pseudo_pattern): Change the second parameter from
        instruction's opcode to byte code.
        (nds32_elf_build_relax_relation): Add new bfd_boolean parameter
        `pseudo_hint'.
        (nds32_lookup_pseudo_opcode): Fix the overflow issue.
        (enum nds32_insn_type): Add N32_RELAX_ALU1 and N32_RELAX_16BIT.
        (nds32_elf_record_fixup_exp, relax_ls_table, hint_map,
        nds32_find_reloc_table, nds32_match_hint_insn, nds32_parse_name):
        Updated.
        * config/tc-nds32.h (MAX_RELAX_NUM): Extend it to 6.
        (enum nds32_relax_hint_type): Merge NDS32_RELAX_HINT_LA and
        NDS32_RELAX_HINT_LS into NDS32_RELAX_HINT_LALS. Add
        NDS32_RELAX_HINT_LA_PLT, NDS32_RELAX_HINT_LA_GOT and
        NDS32_RELAX_HINT_LA_GOTOFF.
