--- Comment #3 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
Confirmed, slightly more cleaned up example:

#include <arm_neon.h>
#include <arm_sve.h>
#include <arm_neon_sve_bridge.h>

int16x8_t
convolve4_4_x (uint16x8x2_t permute_tbl, svint16_t res)
{
    return svget_neonq_s16 (
        svtbl_s16 (res,
                   svset_neonq_u16 (svundef_u16 (), permute_tbl.val[0])));
}
