Detailed Description

A basic instantiation of a breakpoint table.

This object allows breakpoints to registered in the table via either

• registerPcodeCallback() or = registerAddressCallback()

Breakpoints are stored in map containers, and the core BreakTable methods are implemented to search in these containers

Constructor & Destructor Documentation

BreakTableCallBack()

BreakTableCallBack::BreakTableCallBack ( Translate *  t )

inline

Basic breaktable constructor.

The break table needs a translator object so user-defined pcode ops can be registered against by name.

Parameters

t	is the translator object

Member Function Documentation

doAddressBreak()

bool BreakTableCallBack::doAddressBreak ( const Address &  addr )

virtual

Invoke any breakpoints for the given address.

This routine examines the address based container for any breakpoints associated with the given address. If one is found, its addressCallback method is invoked.

Parameters

addr	is the address being checked for breakpoints

Returns

true if the breakpoint exists and returns true, otherwise return false

Implements BreakTable.

doPcodeOpBreak()

bool BreakTableCallBack::doPcodeOpBreak ( PcodeOpRaw *  curop )

virtual

Invoke any breakpoints for the given pcode op.

This routine examines the pcode-op based container for any breakpoints associated with the given op. If one is found, its pcodeCallback method is invoked.

Parameters

curop

is pcode op being checked for breakpoints

Returns

true if the breakpoint exists and returns true, otherwise return false

Implements BreakTable.

registerAddressCallback()

void BreakTableCallBack::registerAddressCallback	(	const Address &	addr,
		BreakCallBack *	func
	)

Register an address based breakpoint.

Any time the emulator is about to execute (the pcode translation of) a particular machine instruction at this address, the indicated breakpoint is invoked first. The break table does not assume responsibility for freeing the breakpoint object.

Parameters

addr	is the address associated with the breakpoint
func	is the breakpoint being registered

registerPcodeCallback()

void BreakTableCallBack::registerPcodeCallback	(	const string &	name,
		BreakCallBack *	func
	)

Register a pcode based breakpoint.

Any time the emulator is about to execute a user-defined pcode op with the given name, the indicated breakpoint is invoked first. The break table does not assume responsibility for freeing the breakpoint object.

Parameters

name	is the name of the user-defined pcode op
func	is the breakpoint object to associate with the pcode op

setEmulate()

void BreakTableCallBack::setEmulate ( Emulate *  emu )

virtual

Associate an emulator with all breakpoints in the table.

This routine invokes the setEmulate method on each breakpoint currently in the table

Parameters

emu	is the emulator to be associated with the breakpoints

Implements BreakTable.
