Abstract

This paper presents FIT, a Flexible open-source binary code Instrumentation Toolkit. Unlike existing tools, FIT is truly portable, with existing backends for the Alpha, x86 and ARM architectures and the Tru64Unix, Linux and ARM Firmware execution environments. This paper focuses on some of the problems that needed to be addressed for providing this degree of portability. It also discusses the trade-off between instrumentation precision and low overhead.
