Abstract

This is a follow-on to my 1988 PLDI paper, Control-Row Analysis in Scheme [9]. I use the method of abstract semantic interpretations to explicate the control-flow analysis technique presented in that paper. I begin with a denotational semantics for CPS I then present an alternate semantics that precisely expresses the control-flow analysis problem. I abstract this semantics in a natural way, arriving at two different semantic interpretations giving approximate solutions to the flow analysis problem, each computable at compile time. The development of the final abstract semantics provides a clear, formal description of the analysis technique presented in Control-How Analysis in Scheme.
