9047         (representing vec_all_ne) to remove the previously described first

9072         (V16QI, V8HI, V4SI), correct a typo in the code emitted for this
9073         define_insn pattern.
9074         (*vsx_ne_<mode>_p): For modes VSX_F (V4SF and V2DF), remove this
9075         define_insn pattern because the xvcmpne<VSs>. instruction is not
9076         supported.

9078         instruction is not supported.
