--- Comment #2 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
I think the point here is __lsx_vftintrne_w_s should be changed to return v4i32
instead, as the output indeed should be a v4i32. On the contrary treating the
output as __m128i (v2i64) is quite unsafe. But the change would be an API
break so we cannot implement it.
I'd not recommend people to use -flax-vector-conversions as the GCC
documentation clearly states "this option should not be used for new code."
Maybe the best course is deprecate __lsx_vftintrne_w_s and add something like
__lsx_vftintrne_w_s_2 instead to return a v4i32.
