# Function core::arch::x86::_mm512_castsi128_si512
[−][src]

    pub unsafe fn _mm512_castsi128_si512(a: __m128i) -> __m512i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512f` only.
Expand description

Cast vector of type __m128i to type __m512i; 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.
