1.27.0 · source · pub unsafe fn _mm256_stream_si256(mem_addr: *mut __m256i, a: __m256i)
Available on (x86 or x86-64) and target feature
avx
and x86-64 only.Expand description
Moves integer data from a 256-bit integer vector to a 32-byte aligned memory location. To minimize caching, the data is flagged as non-temporal (unlikely to be used again soon)
§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.
