Hmm. I hadn't thought of that, and missed that point when looking through your previous patches. I think you should have a third hook for that. ARM will need it, but IA-64 doesn't. > Hook gen_ccmp_next needs one more parameter to indicate AND/IOR since they > will generate different instructions. True, I forgot about that while writing the hook descriptions. r~
