Many computer manufacturers now include tools or simulators that allow you to measure the instruction set usage of a user program. Among the methods in use are machine simulation, hardware-supported trapping, and techniques that instrument the object code module by inserting counters in software or using built-in hardware counters. Pick a processor and tools to instrument user programs. (The open source RISC-V architecture supports a collection of tools. Tools such as the Performance API (PAPI) work with x86 processors.) Use the processor and tools to measure the instruction set mix for one of the SPEC CPU2017 benchmarks. Compare the results to those shown in this chapter.
