  Can we just not with the AI-generated illustrations?

  TL:DR: minimize randomness, group variables by access frequency, and unroll loops if your compiler doesn’t do that already

    tl;dr tl;dr: use a modern compiler.

    Do any compilers NOT unroll loops in high optimization modes? I was under three impression this was usually unnecessary.

      No clue, I was just frustrated with how much useless extended metaphor was in the article and thought I’d save people some time

      Really depends on the target, llvm goes between unrollimg and vectorizing cleanly, to unrollimg to a ludicrous degree, to refusing to unroll period.

      Some of it is subtarget specific, but sometimes it’s just weird.

      Gcc is evil incarnate, all it’s passes are at war with each other, loop Canon form often broke vectorization and even unrolling period.

  What about Claude-Aware coding tho? /s
