We expanded (neg x) to (minus const0 x) for LSX FP vectors, this is
wrong because -0.0 is not 0 - 0.0. This causes some Python tests to
fail when Python is built with LSX enabled.
Use the vbitrevi.{d/w} instructions to simply reverse the sign bit
instead. We
We expanded (neg x) to (minus const0 x) for LSX FP vectors, this is
wrong because -0.0 is not 0 - 0.0. This causes some Python tests to
fail when Python is built with LSX enabled.
Use the vbitrevi.{d/w} instructions to simply reverse the sign bit
instead. We are already doing this for LASX and
