<pre>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.</pre>
