Whole Program Paths


<i>Whole program paths (WPP)</i> are a new approach to capturing and representing a program's dynamic---actually executed---control flow. Unlike other path profiling techniques, which record intraprocedural or acyclic paths, WPPs produce a single, compact description of a program's entire control flow, including loop iteration and interprocedural paths.This paper explains how to collect and represent WPPs. It also shows how to use WPPs to find <i>hot subpaths</i>, which are the heavily executed sequences of code that should be the focus of performance tuning and compiler optimization.
