We describe a way to answer these questions, quickly and accurately, without randomized experiments, surveys, focus groups or expert data analysts. Doubly robust estimation protects against the selection bias that is(More)
Scalar replacement is an effective optimization for removing memory accesses. However, exposing all possible array reuse with scalars may cause a significant increase in register pressure, resulting in register spilling and performance degradation. In this paper, we present a low cost method to predict the register pressure of a loop before applying scalar(More)
