I can confirm that there is still grass with Mesa git-e1ae0c3 + LLVM r236436 and diff --git a/src/gallium/drivers/radeon/radeon_llvm_emit.c.old b/src/gallium/drivers/radeon/radeon_llvm_emit.c index 624077c..0f9dbab 100644 --- a/src/gallium/drivers/radeon/radeon_llvm_emit.c.old +++ b/src/gallium/drivers/radeon/radeon_llvm_emit.c @@ -80,6 +80,10 @@ void radeon_llvm_shader_type(LLVMValueRef F, unsigned type) sprintf(Str, "%1d", llvm_type); LLVMAddTargetDependentFunctionAttr(F, "ShaderType", Str); + + if (type != TGSI_PROCESSOR_COMPUTE) { + LLVMAddTargetDependentFunctionAttr(F, "unsafe-fp-math", "true"); + } } I still get GPU faults with The Talos Principle, even with "unsafe-fp-math" enabled now - although not with either of the traces I posted. I also get some garbage rendered / flickering stuff, but I don't think it's related to "unsafe-fp-math". I'll test more and post a new trace when I have time. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
