V just provides an instruction set simulator, that is, something that
can compute the architecturally-visible effects of executing each
instruction.  There is no attempt made to simulate any microarchitural
details (caches etc) -- at least in the core.  The Callgrind and Cachegrind
tools do simulate that kind of thing.  But that's not "core" functionality.
