Debugger options

 Action    name: SetupDebugger
 

This dialog box allows to specify different settings related to the debugger.

Events

  - Suspend on debugging start

      If selected, the debugger will suspend directly once the debugging
      starts.

  - Evaluate event condition on exit

      If selected, the debugger will evaluate the event condition immediately
      before closing the debugging session (once we receive PROCESS_EXITED or
      PROCESS_DETACHED event)

  - Suspend on process entry point

      If selected, the debugger will insert a temporary breakpoint
      at the main entry point of the debugged application.

  - Suspend on thread start/exit

      If selected, the debugger will suspend if a new thread starts
      or if an existing thread terminates.

  - Suspend on library load/unload

      If selected, the debugger will suspend if a new library is
      loaded or if a previously loaded library is unloaded.

  - Suspend on debugging message

      If selected, the debugger will suspend if the debugged application
      generates a message destined to the debugger.

Event condition

      When one or more debug events (see above) are checked then this
      option is used to specify a condition. In the following example,
      the debugger will suspend the process whenever a module with the
      name test.dll is loaded:

 get_event_id() == LIB_LOADED && strstr(get_event_module_name(), "test.dll") != -1

Log

  - Segment modifications

      If selected, the debugger will print information regarding
      segment modifications (creation, deletion, or resizing of
      segments) since the last event. Note that the debugger
      doesn't continuously track segment modifications, but detects
      those only if a debugging event occurs.

  - Thread start/exit

      If selected, the debugger will print a message if a new thread
      starts or if an existing thread terminates.

  - Library load/unload

      if Selected, the debugger will print a message if a new library is
      loaded or if a previously loaded library is unloaded.

  - Breakpoint

      If selected, the debugger will print a message if the debugged process
      reaches a breakpoint.

  - Debugging message

      If selected, the debugger will print debugging messages from
      the application.

Options

  - Reconstruct the stack

If selected, the debugger will try to reconstruct the chain of stack frames, based on information available on the stack and in the function stack variables.

  - Show debugger breakpoint instructions

      If selected, the debugger will show breakpoint instructions inserted
      by the debugger itself. This function is mainly useful if the user
      wants to see the real content of the memory.

  - Use hardware temporary breakpoints

      If selected, IDA will try to use hardware breakpoints for the temporary
      breakpoints used to implement the "step over" and "run to" functionality.
      This feature is useful when debugging read-only or self-modifying code,
      since it does not change the contents of the memory.
      IDA will fall back to software breakpoints if the attempt to set a
      hardware breakpoint fails.

  - Autoload PDB files

      If selected, IDA will invoke the PDB plugin to try to load PDB symbols
      for every new module loaded into process.

  - Set as just-in-time debugger

      If changed from off to on, IDA will try to register itself as a
      just-in-time debugger (invoked by the system in case of application
      crashes) on dialog close.

Edit exceptions

This button allows the user to setup how the debugger will react to specific exceptions.

Reload exceptions

      This button reloads the exception table from the exceptions.cfg
      file.
