Abstract
A method for code optimization includes disassembling object code that has been compiled and linked, and identifying a function in the disassembled code, the function including store and restore instructions with respect to a register. The disassembled code is analyzed to locate a call to the function followed by an instruction to kill the register. The code is modified so as to eliminate the store instruction from the function when the function is invoked by the located call.
