Detailed Description

A collection of breakpoints for the emulator.

A BreakTable keeps track of an arbitrary number of breakpoints for an emulator. Breakpoints are either associated with a particular user-defined pcode op, or with a specific machine address (as in a standard debugger). Through the BreakTable object, an emulator can invoke breakpoints through the two methods

• doPcodeOpBreak()
• doAddressBreak()

depending on the type of breakpoint they currently want to invoke

Member Function Documentation

doAddressBreak()

virtual bool ghidra::BreakTable::doAddressBreak ( const Address &  addr )

pure virtual

Invoke any breakpoints associated with this machine address.

Within the table, the first breakpoint which is designed to work with at this address is invoked. If there was a breakpoint, and if it was designed to replace the action of the machine instruction, then true is returned.

Parameters

addr	is address to test for breakpoints

Returns

true if the machine instruction has been replaced by a breakpoint

Implemented in ghidra::BreakTableCallBack.

doPcodeOpBreak()

virtual bool ghidra::BreakTable::doPcodeOpBreak ( PcodeOpRaw *  curop )

pure virtual

Invoke any breakpoints associated with this particular pcodeop.

Within the table, the first breakpoint which is designed to work with this particular kind of pcode operation is invoked. If there was a breakpoint and it was designed to replace the action of the pcode op, then true is returned.

Parameters

curop

is the instance of a pcode op to test for breakpoints

Returns

true if the action of the pcode op is performed by the breakpoint

Implemented in ghidra::BreakTableCallBack.

setEmulate()

virtual void ghidra::BreakTable::setEmulate ( Emulate *  emu )

pure virtual

Associate a particular emulator with breakpoints in this table.

Breakpoints may need access to the context in which they are invoked. This routine provides the context for all breakpoints in the table.

Parameters

emu	is the Emulate context

Implemented in ghidra::BreakTableCallBack.
