Guarantees that every previous memory reference, including both load and store memory references, is globally visible before any subsequent memory reference.

x64 |
Header file <intrin.h>
Generates a full memory barrier instruction sequence that guarantees load and store operations issued before the intrinsic are globally visible before execution continues. The effect is comparable to but faster than the _mm_mfence intrinsic on all x64 platforms.
On the AMD64 platform, this routine generates an instruction that is a faster store fence than the sfence instruction. For time-critical code, use this intrinsic instead of _mm_sfence only on AMD64 platforms. On Intel x64 platforms, the _mm_sfence instruction is faster.
This routine is only available as an intrinsic.
