It can be nested with an automatically maintained stack of counter and end address registers. It's an ideal candidate for doloop. Unfortunately, gcc presumes that loops - always end with an explicit instriction, and the doloop_begin + always end with an explicit instruction, and the doloop_begin instruction is not a flow control instruction so it can be scheduled earlier than just before the start of the loop. To make matters worse, the optimization pipeline can duplicate loop exit |
