1. A method, comprising: loading source binary code for execution by a computer system, the computer system comprising memory and a processing unit comprising a plurality of registers and at least one store buffer; identifying, during runtime of said source binary code, a plurality of frequently executed memory instructions within said source binary code, the frequently executed memory instructions include a plurality of store instructions and a plurality of load instructions; defining a two stage commit (TSC) region that includes the frequently executed memory instructions and performing binary optimization operations on the plurality of memory instructions within the TSC region; defining a first stage of the two stage commit (TSC) region; wherein, when executed by the processing unit, the plurality of load instructions commit atomically in the first stage, and the plurality of store instructions retire in the first stage; defining a second stage of the TSC region for the frequently executed block of code, wherein the plurality of store instructions commit atomically in the second stage; and allowing at least one additional load or store memory instruction from outside of the TSC region to retire in the second stage of the TSC region.
