System and method for run-time value tracking during execution

A technique for run-time tracking changes to variables and memory locations during code execution to increase efficiency of execution of the code and to facilitate in debugging the code. In one example embodiment, this is achieved by determining whether a received instruction in a trackable instruction during code execution. The trackable instructions can include one or more trackable variables. The trackable instruction is then decoded and a track instruction cache and a track variable cache are then updated with associated decoded trackable instruction and the one or more trackable variables, respectively.
