ed a92941979e 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.
