+To illustrate this more completely, consider what could happen if the code
+contained a load of A either side of the read barrier:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ { A = 0, B = 9 }
+ STORE A=1
+ <write barrier>
+ STORE B=2
+ LOAD B
+ LOAD A [first load of A]
+ <read barrier>
+ LOAD A [second load of A]
+
+Even though the two loads of A both occur after the load of B, they may both
+come up with different values:

+ +-------+ : : : :
+ | | +------+ +-------+

+ | +-------+ | |
+ At this point the read ----> \ rrrrrrrrrrrrrrrrr | |
+ barrier causes all effects \ +-------+ | |
+ prior to the storage of B ---->| A->1 |------>| 2nd |
+ to be perceptible to CPU 2 +-------+ | |
+ : : +-------+
+
+
+But it may be that the update to A from CPU 1 becomes perceptible to CPU 2
+before the read barrier completes anyway:
+
+ +-------+ : : : :
+ | | +------+ +-------+
+ | |------>| A=1 |------ --->| A->0 |
+ | | +------+ \ +-------+
+ | CPU 1 | wwwwwwwwwwwwwwww \ --->| B->9 |

+ +-------+ | |
+ rrrrrrrrrrrrrrrrr | |
+ +-------+ | |
+ | A->1 |------>| 2nd |
+ +-------+ | |
+ : : +-------+
+
+
+The guarantee is that the second load will always come up with A == 1 if the
+load of B came up with B == 2. No such guarantee exists for the first load of
+A; that may come up with either A == 0 or A == 1.
+
+
+READ MEMORY BARRIERS VS LOAD SPECULATION
+----------------------------------------
+
+Many CPUs speculate with loads: that is they see that they will need to load an
+item from memory, and they find a time where they're not using the bus for any
+other loads, and so do the load in advance - even though they haven't actually
+got to that point in the instruction execution flow yet. This permits the
+actual load instruction to potentially complete immediately because the CPU
+already has the value to hand.
+
+It may turn out that the CPU didn't actually need the value - perhaps because a
+branch circumvented the load - in which case it can discard the value or just
+cache it for later use.
+
+Consider:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ LOAD B
+ DIVIDE } Divide instructions generally
+ DIVIDE } take a long time to perform
+ LOAD A
+
+Which might appear as this:
+
+ : : +-------+
+ +-------+ | |
+ --->| B->2 |------>| |
+ +-------+ | CPU 2 |
+ : :DIVIDE | |
+ +-------+ | |
+ The CPU being busy doing a ---> --->| A->0 |~~~~ | |
+ division speculates on the +-------+ ~ | |
+ LOAD of A : : ~ | |
+ : :DIVIDE | |
+ : : ~ | |
+ Once the divisions are complete --> : : ~-->| |
+ the CPU can then perform the : : | |
+ LOAD with immediate effect : : +-------+
+
+
+Placing a read barrier or a data dependency barrier just before the second
+load:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ LOAD B
+ DIVIDE
+ DIVIDE
+ <read barrier>
+ LOAD A
+
+will force any value speculatively obtained to be reconsidered to an extent
+dependent on the type of barrier used. If there was no change made to the
+speculated memory location, then the speculated value will just be used:
+
+ : : +-------+
+ +-------+ | |
+ --->| B->2 |------>| |
+ +-------+ | CPU 2 |
+ : :DIVIDE | |
+ +-------+ | |
+ The CPU being busy doing a ---> --->| A->0 |~~~~ | |
+ division speculates on the +-------+ ~ | |

+ : : ~ | |
+ : : ~ | |
+ rrrrrrrrrrrrrrrr~ | |
+ : : ~ | |
+ : : ~-->| |
+ : : | |
+ : : +-------+
+
+
+but if there was an update or an invalidation from another CPU pending, then
+the speculation will be cancelled and the value reloaded:
+
+ : : +-------+
+ +-------+ | |
+ --->| B->2 |------>| |
+ +-------+ | CPU 2 |
