pub unsafe fn _mm512_castph256_ph512(a: __m256h) -> __m512h🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature
avx512fp16 and x86-64 only.Expand description
Cast vector of type __m256h to type __m512h. The upper 16 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.
