adding support for gdb

adding support for gdb

Post by don.. » Thu, 30 Apr 1992 04:53:47



Does anyone know of any documents/manuals explaining how to add support
for gdb?  I'm writing the back end of a C compiler and will be spitting
code for Motorola 68040, sparc, MIPS R2000 and maybe ibm's RS/6000.

so far there's only the gdb manual that I glanced through, and of course
gcc -S -g

Any help is greatly appreciated.

please email any responses to:


I'll summarize if there's any interest.

thanks,

Chris

1. Interfacing with gdb: How to set a gdb watch point from C++ code?

I have the following code in a third party library:

// GeneralXEventHandler gets called for each event of the types we requested
// in RegisterObject().  We send the event to the Event() routine of the
// object the event belongs to.
void GeneralXEventHandler(Widget, XtPointer object, XEvent *xEvent,
Boolean *)
{
        UI_WINDOW_OBJECT *uObject = (UI_WINDOW_OBJECT *)object;
        // for debug
^^^^^^^^^^^^^^ need a watchpoint right after assignment.
        UI_WINDOW_OBJECT *uObjectDup = (UI_WINDOW_OBJECT *)object;
        if (!uObject->screenID)
                return;
        UI_EVENT event(E_MOTIF, *xEvent);
        if (xEvent->type == KeyPress && event.rawCode == XK_Tab)
                _lastFocusEvent = KeyPress;
        else if (xEvent->type == ButtonPress)
                _lastFocusEvent = ButtonPress;

        if(uObject != uObjectDup) {
                l_fatal("object %p objectdup %p !!!!", uObject, uObjectDup);
        }
        uObject->Event(event);

I want to set a watchpoint on the contents of uObject after
initialization. The function is called quite a bit and I don't want to
do it manually on every call.
Is there a gcc directive to automate this?
