`llvm.nvvm.tex.unified.2d.v4f32.f32` has a vector output, the alias

  __attribute__((device)) float tex2d_ld(tex_t, float, float) asm("llvm.nvvm.tex.unified.2d.v4f32.f32");

needs replacing with

  __attribute__((device)) v4f tex2d_ld(tex_t, float, float) asm("llvm.nvvm.tex.unified.2d.v4f32.f32");

see this revised sample code https://godbolt.org/z/B7rtxR
