+// CHECK_AARCH64: test_vcopy_laneq_f64
+float64x1_t test_vcopy_laneq_f64(float64x1_t a, float64x1_t c) {
+  return vcopy_laneq_f64(a, 0, c, 0);
+// CHECK: fmov {{d[0-9]+}}, {{d[0-9]+}}
+// CHECK-NOT: dup {{d[0-9]+}}, {{v[0-9]+}}.d[0]
+}

vcopy_laneq_f64 should have prototype as below.

float64x1_t vcopy_laneq_f64(float64x1_t a, const int lane1,
float64x2_t b, const int lane2)


And sorry, one more is missing in the list I previously gave you,

float64x2_t vcopyq_laneq_f64(float64x2_t a, const int lane1,
float64x2_t b, const int lane2)


All others LGTM!


Thanks,
