Detailed Description

This class is a simulator Driver that executes the instruction sequence found in a basic block.

Constructor & Destructor Documentation

otawa::sim::BasicBlockDriver::BasicBlockDriver ( BasicBlock *  bb )

inline

BasicBlockDriver constructor.

Parameters

bb	Basic block to simulate.

Member Function Documentation

Address otawa::sim::Driver::lowerRead ( void  )

virtualinherited

Get the lower read address of the last executed instruction.

Returns

Lower read address.

References otawa::Address::null.

Address otawa::sim::Driver::lowerWrite ( void  )

virtualinherited

Get the lower written address of the last executed instruction.

Returns

Lower written address.

References otawa::Address::null.

Inst * otawa::sim::BasicBlockDriver::nextInstruction ( State &  state, Inst *  inst  )

virtual

This method is called each time the simulator needs the next instruction to execute.

Parameters

state	Current state of the simulator.
inst	Next instruction proposed by the simulator. If the simulator does not handle the semantics of instructions, it is juste the next instruction.

Returns

Next instruction to execute or null if there is no more instruction to execute.

Implements otawa::sim::Driver.

virtual bool otawa::sim::Driver::PredictBranch ( State &  state, Inst *  branch, bool  pred  )

inlinevirtualinherited

virtual void otawa::sim::Driver::redirect ( State &  state, Inst *  branch, bool  direction  )

inlinevirtualinherited

void otawa::sim::BasicBlockDriver::terminateInstruction ( State &  state, Inst *  inst  )

virtual

This method is called when an instruction is terminated.

Parameters

state	Current state of the simulator.
inst	Terminated instruction.

Implements otawa::sim::Driver.

Address otawa::sim::Driver::upperRead ( void  )

virtualinherited

Get the upper read address of the last executed instruction.

Returns

Upper read address.

References otawa::Address::null.

Address otawa::sim::Driver::upperWrite ( void  )

virtualinherited

Get the upper written address of the last executed instruction.

Returns

Lower written address.
