Detailed Description

This class is used to drive a simulator.

The simulator will call methods of this class in order to get next instruction to execution or to inform it about a finishing instruction.

Member Function Documentation

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

virtual

Get the lower read address of the last executed instruction.

Returns

Lower read address.

References otawa::Address::null.

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

virtual

Get the lower written address of the last executed instruction.

Returns

Lower written address.

References otawa::Address::null.

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

pure 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.

Implemented in otawa::sim::BBPathDriver, and otawa::sim::BasicBlockDriver.

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

inlinevirtual

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

inlinevirtual

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

pure virtual

This method is called when an instruction is terminated.

Parameters

state	Current state of the simulator.
inst	Terminated instruction.

Implemented in otawa::sim::BBPathDriver, and otawa::sim::BasicBlockDriver.

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

virtual

Get the upper read address of the last executed instruction.

Returns

Upper read address.

References otawa::Address::null.

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

virtual

Get the upper written address of the last executed instruction.

Returns

Lower written address.

References otawa::Address::null.
