Dyninst on the RISC-V: Binary Instrumentation in Support of Performance, Debugging, and Other Tools
DescriptionBinary instrumentation provides the ability to instrument and modify a program after the compilation process has completed. Operating on the binary level allows instrumentation of the program as it was produced by the compiler. In addition, it can operate on programs or libraries for which you may not have the source code. Binary instrumentation is the foundation for a wide variety of tools, including those for performance profiling, debugging, tracing, architectural simulation, and digital forensics. Dyninst is a free and open-source suite of toolkits for building binary analysis and instrumentation tools for architectures that include the x86, ARM, and Power. It is used in tools produced by industry, academia and research labs. This paper describes our efforts to port Dyninst to the RISC-V architecture. We discuss the challenges presented by the RISC-V, our approaches to solving them, and the status of Dyninst on the RISC-V.
