....when checking only for true data dependencies between instructions. As can be seen, the speedups have increased dramatically to a range of 2. 3 As an aside, it is interesting to note that register renaming is necessary not because of the inherent structure of the code itself, but as Slavenburg [Slav 88] points out, because of how the compiler tries to minimize the number of live registers at any given time. Often a compiler will choose a limited number of registers to be used as temporaries or to hold the most active values in a loop [Aho 86] Thus, when one of these values dies, its register ....
