When a branch misprediction in a pipelined processor is discovered, if the mispredicted branch instruction is not the last uncommitted instruction in the pipelines, older uncommitted instructions are checked for dependency on a long latency operation. If one is discovered, all uncommitted instructions are flushed from the pipelines without waiting for the dependency to be resolved. The branch prediction is corrected, and the branch instruction and all flushed instructions older than the branch instruction are re-fetched and executed.
