source · pub unsafe fn _mm512_castph128_ph512(a: __m128h) -> __m512h🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16 #127213)Available on x86-64 only.
Expand description
Cast vector of type __m128h to type __m512h. The upper 24 elements of the result are undefined.
In practice, the upper elements are zeroed. This intrinsic can generate the vzeroupper instruction,
but most of the time it does not generate any instructions.
