1. A processing device comprising: an instruction tracking unit comprising an instruction buffer to store a sequence of executed instructions; and a data trace unit communicably coupled to the instruction tracking unit and comprising a data trace buffer and a decoding module, wherein the data trace buffer is to store a data trace log, and wherein the decoding module is to: determine an order number corresponding to an order in which an instruction was executed relative to other executed instructions that correspond to an instruction type within the sequence of executed instructions; identify, within the data trace log, a first data packet corresponding to a first packet type and sequentially ordered, according to the order number, with respect to data packets of the first packet type within the data trace log; identify, within the data trace log, a second data packet corresponding to a second packet type and sequentially ordered, according to the order number, with respect to data packets of the second packet type within the data trace log; and map the identified first and second data packets to the instruction, wherein at least one of the first or second data packets was generated post-retirement of the instruction.
