Dual Use Memory Management Library

Abstract

A dual-use library that is able to handle calls from programs requiring either reference count or garbage collected memory management is described. This capability may be provided by introducing a new assignment routine, assign( ), and instrumenting the reference count routines responsible for updating an object's reference count—e.g., addReference( ) and removeReference( ) routines. The assign( ), addReferenc( ) and removeReference( ) routines determine, at runtime, which memory management scheme is appropriate and execute the appropriate instructions (i.e., reference count or garbage collection specific instructions). The described dual-use library provides equivalent functionality as prior art two library implementations, but with a significantly lower memory footprint.

Dependencies are inferred from the claim text.
