Replacing store buffers by load buffers in TSO

• We consider the weak memory model of Total Store Ordering (TSO). In the classical definition of TSO, an unbounded buffer is inserted between each process and the shared memory. The buffers contains pending store operations of the processes. We introduce a new model where we replace the store buffers by load buffers. In contrast to the classical model, the buffers now contain load operations. We show that the models have equivalent behaviors in the sense that the processes reach identical sets of states when the input program is run under the two models.
