radv llvm

MMUTFX2053

how can i enable radv llvm shader compiler ? currently there is a bug with aco on starfield, with certain graphics cards there is a missing textures issue.

i tried "RADV_DEBUG=llvm" but the game wont start, i suspect mesa/radv is looking for another version of llvm but im not sure

some extra info, im getting this:

/home/build/YPKG/root/llvm/build/llvm-project-15.0.7.src/llvm/lib/IR/Instructions.cpp:3187: static llvm::CastInst *llvm::CastInst::Create(Instruction::CastOps, llvm::Value *, llvm::Type *, const llvm::Twine &, llvm::Instruction *): Assertion `castIsValid(op, S, Ty) && "Invalid cast!"' failed.

but i have no idea what it is, no experience with llvm

Is there a bug report or issue for the Starfield issue?

all rx400, rx500 and vega gfx card users experience this problem, on linux, i figured out that disabling aco optimizations with "ACO_DEBUG=noopt" everything works fine, but its very slow, and it recompiles the shaders evey single time i open the game.

so if we can use llvm until aco is fixed that would be great
