Abstract: In accordance with embodiments disclosed herein, there is provided systems and methods for tracking the mode of processing devices in an instruction tracing system. The method may include receiving an indication of a change in a current execution mode of the processing device. The method may also include determining that the current execution mode of the received indication is different than a value of an execution mode of a first execution mode (EM) packet previously-generated by the IT module. The method may also include generating, based on the determining that the current execution mode is different, a second EM packet that provides a value of the current execution mode of the processing device to indicate the change in the execution mode for an instruction in a trace generated by the IT module. The method may further include generating transactional memory (TMX) packets having n bit mode pattern in the packet log. The n is at least two and the n bit mode indicates transaction status of the TMX operation.

Abstract: Techniques for an instruction for a Runtime Call operation are described. An example apparatus comprises decoder circuitry to decode a single instruction, the single instruction to include a field for an identifier of an opcode, the opcode to indicate execution circuitry is to execute a no operation when a runtime call destination equals a predetermined value; and execute an indirect call with the runtime call destination as a destination address when the runtime call destination does not equal the predetermined value. Other examples are described and claimed.
