Ahmed Bougacha 66649e00c9 [CodeGen] Combine concat_vector of trunc'd scalar to scalar_to_vector. ... We already do: concat_vectors(scalar, undef) -> scalar_to_vector(scalar) When the scalar is legal. When it's not, but is a truncated legal scalar, we can also do: concat_vectors(trunc(scalar), undef) -> scalar_to_vector(scalar) Which is equivalent, since the upper lanes are undef anyway. While there, teach the combine to look at more than 2 operands.
