The Interprocedural Express-Lane Transformation
Abstract. The express-lane transformation isolates and duplicates frequently executed program paths, aiming for better data-flow facts along the duplicated paths. An express-lane ¤ is a copy of a frequently executed program path such that ¤ has only one entry point at its beginning; ¤ may have branches back to the original code, but the original code never branches into ¤ . Classical data-flow analysis is likely to find sharper data-flow facts along an express-lane, because there are no join points. This paper describes several variants of interprocedural express-lane transformations; these duplicate hot interprocedural paths, i.e., paths that may cross procedure boundaries. The paper also reports results from an experimental study of the effects of the express-lane transformation on interprocedural range analysis.
