A method, performed by a computer, for optimizing a computer program having a plurality of instructions that form a loop. The loop has a first block and a second block. The first block has at least one instruction for using a variable and the second block has an ambiguous definition instruction for defining the variable. A load instruction for loading the variable into a register is inserted prior to the plurality of instructions that form the loop. In addition, at least one instruction for using the variable is replaced with an instruction for using the register. Further, a load instruction for loading the variable into the register is inserted after the ambiguous definition instruction.
