PEBS can capture machine state regs at retiremnt of the sampled instructions. When precise sampling is enabled on an event, PEBS is used, so substitute the interrupted state with the PEBS state. Note that not all registers are captured by PEBS. Those missing are replaced by the interrupt state counter-parts.
