    pub unsafe fn _mm512_stream_si512(mem_addr: *mut i64, a: __m512i)

🔬This is a nightly-only experimental API. (`stdarch_x86_avx512` #111137)
Available on (x86 or x86-64) and target feature `avx512f` and x86 only.
Expand description

Store 512-bits of integer data from a into memory using a non-temporal memory hint. mem_addr must be aligned on a 64-byte boundary or a general-protection exception may be generated.

Intel’s documentation

## §Safety of non-temporal stores

After using this intrinsic, but before any other access to the memory that this intrinsic mutates, a call to `_mm_sfence` must be performed by the thread that used the intrinsic. In particular, functions that call this intrinsic should generally call `_mm_sfence` before they return.

See `_mm_sfence` for details.
