@gfxstrand@social.treehouse.systems on amd it means unless you mark a bda pointer as RO, accesses through it can't be scalarized :'(
(this is not a tremendous problem, it is just what triggered me to walk through the whole pipeline...)

@dotstdy@mastodon.social Oh, that’s just because AMD’s caching situation in bonkers. But also, marking stuff appropriately RO will probably help NVIDIA, too, because it’ll enable their constant caching mode which is a lot faster. (Though it’s less bonkers than AMD’s scalar cache. 😂)
