Interesting idea. I think it means using another register to permanently hold the HANDLER_BASE though? The dispatch sequence is only 4 instructions. I tried it as a delta encoding, requiring another add instruction on every dispatch, but that is an approx. 5% penalty. So I was hoping that putting it at absolute address < 64KB I could do the sequence without another add.
