Expand description
Stores a 128-bit floating point vector of [2 x double]
to a 128-bit
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.
