You can bind this defun to a key of your choice:

(defun clean-comint-buffer()
  (interactive)
  (delete-region (point-min)
                 (save-excursion
                   (goto-char (point-max))
                   (forward-line 0)
                   (point))))

It works for gdb and other comint-based modes (shell, interactive sql, etc...) that sometimes tend to grow with lines no longer useful.

EDIT

For binding this function to all comint buffers (gdb buffer is one of those), you may use (assuming you want C-c g):

(add-hook 'comint-mode-hook
          (lambda ()
            (local-set-key "\C-cg" 'clean-comint-buffer)))

You can clear the whole buffer by typing C-x h C-w SPC RET.

Type C-l C-l. This will scroll the buffer so that the current line is at the top of the window.
