Abstract

Register Allocation for Accurate Garbage Collection of C++ S. Satishkumar* M.S. Creative Component Accurate garbage collection of C++ requires that every memory location and every register be known to contain either a pointer or a non-pointer. In order to minimize the run-time overhead of tagging memory locations and registers, techniques for partitioning memory and registers into separate classes dedicated independently to the representation of pointers and non-pointers respectively have been developed. This paper describes the implementation and performance of a specially designed register allocator for the GNU g++ compiler. * Portions of this paper were excerpted from "Code Generation to Support Efficient Accurate Garbage Collection of C++ on Stock Hardware", a paper currently being prepared for publication by Kelvin Nilsen, Ravichandran Ganesan, Satish Guggilla, Satish Kumar, and Kannan Narasimhan
