It was supposed to have two latency definitions at most (one in

If you really need more one bypass for insn pair, I could implement
this. Please, let me know. In this case semantics of choosing latency
time could be
o time in first bypass occurred in pipeline description whose condition
returns true
o time given in define_insn_reservation
Maxim and I encountered the same problem, and I believe we won't be the last
two unlucky guys. Can you please implement the extended semantics, which looks
good to me?
Ok. I think that patch will be ready tomorrow or day after tomorrow.
