        * gdbarch.sh: Move include of dis-asm.h so it is generated earlier
        in gdbarch.h.
        (TARGET_PRINT_INSN): Multiarch.
        * gdbarch.h: Regenerate.
        * gdbarch.c: Regenerate.

        * arch-utils.c (legacy_print_insn): New function.
        * arch-utils.h (legacy_print_insn): Export.

        * cris-tdep.c (cris_delayed_get_disassembler): Use
        TARGET_PRINT_INSN, instead of tm_print_insn.
        * d10v-tdep.c (print_insn): Ditto.
        * d30v-tdep.c (print_insn): Ditto.
        * m32r-tdep.c (dump_insn): Ditto.
