That is not correct. I'm just restoring previous behaviour. > Right now, we have the assumption that we can derive the Esize from the RM_Size > rounded up to the alignment. That completely ignores padding. > If necessary, we can pass both Esize and RM_Size, but the current change seems > like it would break other targets. Those targets would have been broken before. Since nobody appeared to complain so far, those targets don't exit.
