If the load_interpolated_input is scalarized, we would be too conservative about deciding the tex instruction wasn't a candidate to pre-fetch: vec1 32 ssa_0 = load_const (0x00000000 /* 0.000000 */) vec2 32 ssa_1 = intrinsic load_barycentric_pixel () (0) /* interp_mode=0 */ vec1 32 ssa_2 = intrinsic load_interpolated_input (ssa_1, ssa_0) (0, 0) /* base=0 */ /* component=0 */ /* packed:v_uv,v_uv1 */ vec1 32 ssa_3 = intrinsic load_interpolated_input (ssa_1, ssa_0) (0, 1) /* base=0 */ /* component=1 */ /* packed:v_uv,v_uv1 */ vec2 32 ssa_8 = vec2 ssa_2, ssa_3 vec4 32 ssa_9 = tex ssa_8 (coord), 0 (texture), 0 (sampler) Really we don't care that the texcoord components come from different load_interpolated_input instructions, just that they have consecutive varying offsets.
