    sees IR that it could apply to then one would think one could just have some kind of analyzer tool
    based on compiler code generation level analysis that looks for relevant spots and simply emits LINT
    or something suggesting "Hey this code area could possibly be sped up" and then people could
    attend to profiling / optimizing those areas specifically if there's something that could be done beyond
    letting the compiler optimization work.
    I think this exists.

      I mean, I'm not clever enough to write code with SIMD intrinsics usually, but just knowing that it's not optimal code to begin with helps. At least I can then either pass it to a smart person or look for better alternative ways to perform something.
