pub unsafe fn _mm256_zextph128_ph256(a: __m128h) -> __m256h🔬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 __m128h. The upper 8 elements of the result are zeroed.
This intrinsic can generate the vzeroupper instruction, but most of the time it does not generate
any instructions.
