Example Output

call void @dx.op.rawBufferStore.f32(i32 140, %dx.types.Handle %Exposure_UAV_structbuf, i32 1, i32 0, float %75, float undef, float undef, float undef, i8 1, i32 4)
call void @dx.op.rawBufferStore.f32(i32 140, %dx.types.Handle %Exposure_UAV_structbuf, i32 2, i32 0, float %FMin, float undef, float undef, float undef, i8 1, i32 4)

Exposure[1] = {_75};
Exposure[2] = {_FMin};
