History
Nicolai Haehnle 634941ba37 AMDGPU: llvm.SI.fs.constant is a source of divergence 
Summary:
This intrinsic is used to get flat-shaded fragment shader inputs. Those are
uniform across a primitive, but a fragment shader wave may process pixels from
multiple primitives (as indicated by the prim_mask), and so that's where
divergence can arise.
