It appears I am missing a line in the code I posted:
#include
extern void printv(__m128 m);
int main()
{
__m128 m = _mm_set_ps(1.0f, 2.0f, 3.0f, 4.0f);
m = _mm_shuffle_ps(m, m, 0xC9); // Those two
ions.

I would like to add that changing
void printv_f32(const float32x4_t &v)
into:
void printv_f32(float32x4_t v)
makes the problem go away, but the generated code is suboptimal.

Mikael's patch seems to do that trick as well as producing very nice assembly.
