@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 @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.
