Method and system using hardware assistance for instruction tracing with secondary set of interruption resources

摘要: A method, system, apparatus, and computer program product is presented for processing instructions. processor able to receive multiple types of interruptions while executing The can include aborts, faults, interrupts, traps. has a plurality interruption resources, such as control registers, in which type be associated with specific resource. In response receiving an interruption, the saves state information into resource based on received after invokes handler process interruption. save first saving second resource, thereby allowing single-step taken branch so that other traced.
