The BREAKPOINT EXCEPTION handler

7.5: The BREAKPOINT EXCEPTION handler

This handler is connected to the BREAKPOINT exception (INT3 on Intel Ix86). Each time the debugger wants to place a software breakpoint in the debuggee, a debuggee opcode is temporarily replaced by an instruction causing BREAKPOINT exception (the ``INT 3'' instruction on Intel ix86). When ``INT 3'' is executed, the BREAKPOINT handler is executed. Otherwise, the exception processing is the same than the one described in previous section.
