maybe something like https://dlang.org/phobos/core_bitop.html#.volatileLoad and https://dlang.org/phobos/core_bitop.html#.volatileStore

I am converting a C code that uses this macro:

#define CompletePastWritesBeforeFutureWrites _WriteBarrier(); _mm_sfence()

As far as I see core.atomic:atomicFence() is the equivalent of _mm_sfence() but I can't find what would be the equivalent of _WriteBarrier(). As far as I understand it is used just to tell the compiler it can't rearrange instructions during optimizations so subsequent memory writes happen before previous ones. Same for _ReadBarrier().
