This works, but is probably not the best way to do it:

(defun th-outline-regexp ()
   "Calculate the outline regexp for the current mode."
   (let ((comment-starter (replace-regexp-in-string
                           "[[:space:]]+" "" comment-start)))
     (when (string= comment-starter ";")
       (setq comment-starter ";;"))
     (when (string= comment-starter "#")
       (setq comment-starter "##"))
     (when (eq major-mode 'verilog-mode)
       (setq comment-starter "\\s-*//"))     ;; for verilog-mode, define 
comment-starter as any amount of whitespace followed by "//". This 
allows indented comments as outline levels
     (concat comment-starter " [*]+ ")))
