   As noted in the article, Apple solved this problem six years ago by simply adding an x86-compatible memory ordering mode to their chip when x86 emulation became important. Yet another way Apple's chips lead the industry.

      And as noted in the article, while that helps a lot with most of the issues, there are some corner-cases they still don't handle.

         Yeah, I thought that was interesting. Knowing Apple they must’ve profiled a ton of code and decided the hit from not “fixing“ that wasn’t worth enough.

         The M chips were already so much faster then the Intel chips Apple was using before (except on Mac Pro maybe) that it was probably still a net win.
