Seems like these changes only benefit you if you have an Intel processor. If you have an AMD or Arm processor, you won’t see any difference.

Also, interesting to see assembly again after many years. Haven’t touched that since college during a compilers and assembly course.

Edit: never mind, amd has implemented these “sha-ni” instructions since “Zen” [1]
