Odd - I thought that this setup-semantics stuff was just an
experimental stub, like a bunch of other cgen constructs.
Normally I would try getting this sort of work done outside
cgen, within the hand-written portion of instruction execution
loops.
As to the original question of who increments the PC, this
depends on several parameters: whether sid or sim family,
whether scache or pbb generated kernel. AFAIK the
setup-semantics stuff is never actually *necessary*.
