fori_loop is not optional. I initially wrote the outer loop as for q_block in range(num_q_blocks): and it compiled fine. But XLA unrolled every iteration into the graph, and compilation took forever for large sequences. fori_loop tells XLA this is a real loop. The tradeoff: the body must be a function, and there’s no breaking early. Part 4’s Triton kernel could stop the KV loop at q_end for causal early-stop. Here all K blocks get processed and the causal mask zeros out future positions — more wasted compute, but the loop structure stays simple for XLA.
