p4 think itself very smart. but p4 not so smart as shamiqa. p4 think branch go false false false true true true. but branch go false true false false true true. p4 make bad guess. p4 get confuse then p4 go very slow. shamiqa want to make p4 no more guess but wait until know for sure.
branch prediction very bad idea unless code very simple. shamiqa no write simple code! you tell shamiqa how to make p4 no more guess when run shamiqa code, yes?
speculative execution even more worse idea unless code very simple. shamiqa no write simple code!! you tell shamiqa how to make p4 no more guess when run shamiqa code, yes?
out-of-order execution most worst idea of all unless code very simple. shamiqa no write simple code!!! you tell shamiqa how to make p4 no more guess when run shamiqa code, yes?
