only.Expand description
Stores a 64-bit integer value in the specified 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.
