Abstract
Official abstract text for this publication.
The present invention extends to methods, systems, and computer program products for emulating pointers. Pointers can be emulated by replacing the pointers with a <variable#, offset> pair and replacing each dereference site with a switch on the tag and a switch body that executes the emulated pointer access on the corresponding variable the pointer points to. Data flow optimizations can be used to reduce the number of switches and/or reduce the number of cases which need be considered at each emulated pointer access sites.
First claim
Opening claim text (preview).
What is claimed: 1. At a computer system including one or more processors and system memory, a method for emulating pointers, the method comprising: an act of accessing a plurality of lower level instructions of lower level code translated from corresponding statements and expressions of higher level code, the plurality of lower level instructions including lower level instructions representing statements and expressions from the higher level code that define a plurality of differ…
