Abstract
We present a static analysis that estimates reusable memory cells and a source-level transformation that adds explicit memory reuse commands into the program text. For benchmark ML programs, our analysis and transformation system achieves a memory reuse ratio from 5.2% to 91.3% and reduces the memory peak from 0.0% to 71.9%. The small-ratio cases are for programs that have a number of data structures that are shared. For other cases, our experimental results are encouraging in terms of accuracy and cost. Major features of our analysis and transformation are: (1) polyvariant analysis of functions by parameterization for the argument heap cells; (2) use of multiset formulas in expressing the sharings and partitionings of heap cells; (3) deallocations conditioned by dynamic flags that are passed as extra arguments to functions; (4) individual heap cells as the granularity of explicit memory reuse. Our analysis and transformation system is fully automatic.
