as whenever they do - they probable basically use The shop buffer, Nevertheless they flush it along with the instruction pipeline prior to the load and await it to drain following, and have a lock over the cacheline which they just take as portion o the load, and release as A part of The shop - all to ensure that the cacheline will not go away between and that nobody else can see The shop buffer contents although this is occurring.
