% DXC generates very strange code here, the first component is emitted with:
%    call void @dx.op.storeOutput.f32(i32 5, i32 0, i32 0, i8 0,
%            float sitofp (ppc_fp128 0xM3FF00000000000000000000000000000 to float))
% I don't know what's going on here, but the downstream compilers clearly don't
% like it: NVIDIA fails to create the PSO, AMD returns zero (instead of expected
% one) and WARP loses the device; it's not our bug, we can ignore it.
