Here are my two cents:

On other processors, a compiler could make the assumption that unless it sees an explicit memory barrier (or some code which it cannot analyse) it can just cache the value of a variable (whether or not declared as volatile).

(repost) No, the C++ standard does not grant the compiler such freedom, although the MMU can certainly use a cached copy. ;-)
