I'm pretty rusty so excuse me if I'm spouting nonsense, but I think MRS (read register file) has a dependency on the value of Q (so q/add/sub/clear) and operations which OR a new value with Q (q/add/sub [do q |= 0 or q |= 1) have a dependency on operations which change the register file (MSR). Basically qadd and qusb commute on Q. I'm a bit fuzzy on the details, but I think this means that you just have to stall/predict when there's about to be a branch anyway. Please correct me/clarify if I'm wrong.
