For CS_ETM_TRACE_ON packet, its fields 'packet->start_addr' and 'packet->end_addr' equal to 0xdeadbeefdeadbeefUL which are emitted in the decoder layer as dummy value, but the dummy value is pointless for branch sample when we use 'perf script' command to check program flow. This patch is a preparation to support CS_ETM_TRACE_ON packet for branch sample, it converts the dummy address value to zero for more readable; this is accomplished by cs_etm__last_executed_instr() and cs_etm__first_executed_instr(). The later one is a new function introduced by this patch.
