In the DFA pipeline description, is the latency time equal to the number of cycles between instruction issue and instruction results or is it number of cycles btw instr issue and intruction results + 1 (the instr issue cycle also being counted) ?
If instr I is issued cycle = t and the results are usable in cylce t+1, should the latency in define_insn_reservation be 1 or 0?
