--- Comment #3 from Bas Nieuwenhuizen <bas at basnieuwenhuizen.nl> ---
So top level is a f32 -> i16 bitcast:

Cannot select: 0x7e8d8750: i16 = bitcast 0x7e8d8af8

which is not allowed. Is in LLVM source:

%76 = call float @llvm.amdgcn.buffer.load.f32(<4 x i32> %75, i32 0, i32 %74, i1
false, i1 false) #3
  %77 = bitcast float %76 to i16

Happens in the nir:

vec1 16 ssa_115 = intrinsic load_ssbo (ssa_113, ssa_114) () ()

I'm really inclined to say it is our lacking 16-bit support.
