Thread memorybarrier
In computing, a memory barrier, also known as a membar, memory fence or fence instruction, is a type of barrier instruction that causes a central processing unit (CPU) or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction. This typically means that operations issued prior to the barrier are guaranteed to be performed before operations issued after the barrier. WebNote that I've made MemoryBarrier() a no-op on Phi. I'm a bit nervous about this. Although the chip is in-order, there's a risk that the compiler may re-order instructions in an …
