The movn instruction is definitely a mips4 one. It
is possible to go two ways:

1. Recode the macro to use the lowest common denominator
    of mips2 instructions.

2. Detect at compile time what ISA level is supported and
    then conditionally compile appropriately.

I am happy to work on either of these two options.
I suspect option 2 is better. Any guidance from more
experienced mips developers than I would be greatly
appreciated.

Thanks for the bug report and the patch. Is there  a
way to implement the code using movn with mips2
instructions?
