Constructor & Destructor Documentation

SimPoint::SimPoint ( const SimPointParams *  params)

Definition at line 45 of file simpoint.cc.

Member Function Documentation

void SimPoint::init ( )
virtual

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.

Reimplemented from SimObject.

Definition at line 65 of file simpoint.cc.

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.

Definition at line 78 of file simpoint.cc.

Referenced by regProbeListeners().

void SimPoint::regProbeListeners ( )
virtual

Register probe listeners for this object.

No probe listeners by default, so do nothing in base.

Reimplemented from SimObject.

Definition at line 69 of file simpoint.cc.

References ProbeListenerObject::listeners, and profile().
