Abstract
One embodiment of a method for eliminating redundant operations establishing common properties includes identifying a first virtual register storing a first value having a common property. The method may assign the first virtual register to use a real register. The method may further identify a second virtual register storing a second value also having the common property. The method may assign the second virtual register to use the same real register after the first value is no longer live. As a result of assigning the second virtual register to the first real register, the method may eliminate an operation configured to establish the common property for the second virtual register since this operation is redundant and is no longer needed.
