Oh sorry, it is my typo issue, it should be:

  "... insn name is only useful in tic4x_insn_check() ..."

And for me, we also need strncat() instead of the strcat() (excuse me
for not noticing about it in the original fixing strncat issue patch):

      strcat (insn->name, "_");
      strncat (insn->name, str, TIC4X_NAME_MAX - 1 - strlen (insn->name));


Thanks.
