As far as I know, it doesn't matter anywhere. We don't even bother to have perfect harmony between integer modes in hard registers -- think about what happens when we drop all the subregs on the floor post-reload. Yes, it's probably an error if we don't have compatible modes between def and use, but nothing is going to check for that. r~
