All this part looks fine, but there I think there is too much copy and
paste for things that basically do:
- Split the argument into n parts of m bits
- Call a function on all parts
- Reassemble all the parts
If you want you might try to create a macro doing that. With a for loop
like you did in helper_subuh_r_ob(), and passing to the macro the values
of n, m and the function, you can probably use only one macro for most
of this.

All these functions should check for rd, rs and rt being 0. For that I
think it's better to call a function with the needed arguments (like for
example gen_loongson_integer()) and move all that code there. That way
you can add the check for rd, rs, rt in the common part, as well as the
check_dsp part.
