difference between vmovq_n_f32() and vdupq_n_f32()

Question

I'm now learning arm neon. I find that vmovq_n_f32() and vdupq_n_f32() seems to do the same thing, they all initialize a float32x4_t variable with some value. So what's their difference?

I have tried using both functions, and they output the same value.

Answer 1

They map to the same thing, so there is no difference
