docs(twitter): add 1776597200073568623 corpus (NOTimothyLottes 'AMD GPU shader compiler isn't doing' book)

7-post thread with @MartinJIFuller + @SebAaltonen, April 2024, 35 likes, 4445 views, 4 media (3 JPGs + 1 MP4). 'This is how slow code feels like' (huge switch table in compiled shader) vs 'this is how clever you feel after finding the optimization' (manual bit extract + AND). @SebAaltonen: 'Sad that the compiler isn't doing this for us in 2024.' NOTimothyLottes: 'On mastodon.gamedev.place 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.' High engagement because of the contrarian framing.

+This is how slow code feels like:

+@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.
