    PR target/49621
    * config/rs6000/rs6000.c (rs6000_emit_vector_cond_expr): Use
    CONST0_RTX (dest_mode) instead of const0_rtx as second operand
    of NE.
    * config/rs6000/vector.md (vector_select_<mode>,
    vector_select_<mode>_uns): Change second operand of NE to
    CONST0_RTX (<MODE>mode) instead of const0_rtx.
    * config/rs6000/altivec.md (*altivec_vsel<mode>,
    *altivec_vsel<mode>_uns): Expect second operand of NE to be
    zero_constant of the corresponding vector mode.
    * config/rs6000/vsx.md (*vsx_xxsel<mode>, *vsx_xxsel<mode>_uns):
    Likewise.

    * gcc.target/powerpc/altivec-34.c: New test.
