MODERATORS
perf and valgrind might be good places to start. Although, some programs aren't going to have the exact same executed instruction count between runs, and it's possible that executed instruction count can depend on the exact CPU that's running. You can probably mitigate the latter by running valgrind and the program inside of QEMU.
Thank you! That's exactly the kinda thing I was looking for!
