H A Dlocking.txt120 One way to fix this is to use smp_load_acquire() and smp_store_release()
126 r0 = smp_load_acquire(&flag);
140 The smp_load_acquire() guarantees that its load from "flags" will
144 The smp_store_release() pairs with the smp_load_acquire(), thus ensuring
150 this case, via the smp_load_acquire() and the smp_store_release().

237 store, while the smp_load_acquire macro orders the load against any
250 use of smp_store_release() and smp_load_acquire(), except that both
295 and to use smp_load_acquire() instead of smp_rmb(). However, the older
