This is how slow code feels like:

And this is how clever you feel after finding the optimization:

@SebAaltonen Sad that the compiler isn’t doing this for us in 2024

@MartinJIFuller @SebAaltonen On https://mastodon.gamedev.place/@NOTimothyLottes I'm collecting posts with AMD GPU disassembly dumps for a book on everything the shader compiler 'isn't doing'. Constant AMD GPU compiler perf bug SPAM is a key part of my online strategy to keep a low follower count.

@NOTimothyLottes @SebAaltonen A worthwhile project, knowledge well worth sharing, but is a book the right format? Perhaps yes, just thinking out loud.

@NOTimothyLottes @SebAaltonen @MartinJIFuller Oh sick, I'm deep in optimising shaders in an AAA game for GCN hardware right now (You can probably guess the platform(s)) so this is super relevant to me. 😅
Going to give it all a thorough read, I'm after all the GCN info I can find right now.
