(ix86_expand_vector_init_general): Ditto. Use SImode instead of word_mode for logic operations when GET_MODE_SIZE (mode) < UNITS_PER_WORD. (expand_vec_perm_even_odd_1): Assert that V2HI mode should be implemented by expand_vec_perm_1. (expand_vec_perm_broadcast_1): Assert that V2HI and V4HI modes should be implemented using standard shuffle patterns. (ix86_vectorize_vec_perm_const): Handle V2HImode. Add V4HI and V2HI modes to modes, implementable with shuffle for one operand. * config/i386/mmx.md (*punpckwd): New insn_and_split pattern. (*pshufw_1): New insn pattern. (*vec_dupv2hi): Ditto. (vec_initv2hihi): New expander. gcc/testsuite/ PR target/100637 * gcc.dg/vect/slp-perm-9.c (dg-final): Adjust dumps for vect32 targets.
