--- Comment #2 from nsz at gcc dot gnu.org ---
e.g.

#include <arm_neon.h>

float32x2_t
foo (float32x2_t v0, float32x4_t v1)
{
  return vmulx_laneq_f32 (v0, v1, 0);
}

used to get translated to

foo:
        fmulx   v0.2s, v0.2s, v1.s[0]
        ret

now it is

foo:
        adrp    x0, .LC0
        ldr     q2, [x0, #:lo12:.LC0]
        tbl     v1.16b, {v1.16b}, v2.16b
        fmulx   v0.2s, v0.2s, v1.2s
        ret
        .size   foo, .-foo
        .section        .rodata.cst16,"aM",@progbits,16
        .align  4
.LC0:
        .byte   0
        .byte   1
        .byte   2
        .byte   3
        .byte   0
        .byte   1
        .byte   2
        .byte   3
        .byte   0
        .byte   1
        .byte   2
        .byte   3
        .byte   4
        .byte   5
        .byte   6
        .byte   7
