Abstract

Naive program transformations can have surprising effects due to the interaction between introduced identifier references and previously existing identifier bindings, or between introduced bindings and previously existing references. These interactions can result in the inadvertent binding, or capturing, of identifiers. A further complication results from the fact that the transformed program may have little resemblance to the original program, making correlation of source and object code difficult. We address both the capturing problem and the problem of source-object code correlation. Previous approaches to the capturing problem have been both inadequate and overly restrictive, and the problem of source-object code correlation has been largely unaddressed. Our approach is based on a new algorithm for implementing syntactic transformations...
