Is there a tool where you can check how many instructions your program, with a set input, required to execute the task?

Imagine this, given an x86 C/C++/Rust compiler we all agree upon, and a set of inputs we also share, produce a program that counts - say - the median length of the arrays given or something. After which we'll run our programs in a profiler of sorts that tells us 'this program achieved the task in 1,104,687 cumulative instructions' and we'll compete based on that metric.

It wouldn't really matter what processor you use because the target is the same and so is the compiler.

Is what I suggest possible? It'd be a nice conciliation between platform independence and speed measuring.
