aykevl added a comment.

I have found that my fix isn't complete, it can result in broken code because the register allocator does not know that `R31R30` is in use between `ADJCALLSTACKDOWN` and `STDWSPQRr` and might use it as the value operand for the `STDWSPQRr` instruction.

...I'm not sure how to fix this.
