[][src]Function core::arch::x86_64::_mm512_castpd128_pd512

pub unsafe fn _mm512_castpd128_pd512(a: __m128d) -> __m512d
🔬 This is a nightly-only experimental API. (stdsimd #48556)
This is supported on x86-64 and target feature avx512f only.

Cast vector of type __m128d to type __m512d; the upper 384 bits of the result are undefined. This intrinsic is only used for compilation and does not generate any instructions, thus it has zero latency.
