Before revision:  Motivated by the rapid recent expansion of so-called Internet of Things (IoT) devices, we are particularly interested in improving the execution time of code running on embedded system architectures. We demonstrate the effectiveness of our approach on code compiled by the GNU C Compiler (GCC) for the ARM Cortex-M3 (CM3) processor;
After revision:  We begin by developing our approach on code compiled by the GNU C Compiler (GCC) for the ARM Cortex-M3 (CM3) processor;
