init() is called after all C++ SimObjects have been created and all ports are connected.
Initializations that are independent of unserialization but rely on a fully instantiated and connected SimObject graph should be done here.

void SimPoint::profile | ( | const std::pair< SimpleThread *, StaticInstPtr > & | p | ) |
Profile basic blocks for SimPoints.
Called at every macro inst to increment basic block inst counts and to profile block if end of block.
